Description

Technical Field

[0001] This utility model relates to the field of stainless steel strip technology, specifically to a stainless steel strip structure with a scratch-resistant and wear-resistant surface. Background Technology

[0002] With the rapid development of modern industrial technology, stainless steel strip, as an important basic material, is widely used in many fields such as construction, automobiles, electronics, and aerospace. However, traditional stainless steel strip often falls short in terms of surface hardness and wear resistance, making it difficult to meet the needs of some special environments. Existing stainless steel strip technology mainly suffers from the following defects: First, the surface hardness is not high enough, making it difficult to resist scratches and wear from external hard objects; second, its wear resistance is poor, and wear marks easily appear on the surface after long-term use, affecting aesthetics and performance; third, the bonding strength between layers is not strong enough, making it prone to peeling and leading to a decline in the overall performance of the strip. Utility Model Content

[0003] The purpose of this invention is to provide a stainless steel strip structure with a scratch-resistant and wear-resistant surface to solve the problems of easy scratching, wear and weak bonding of existing stainless steel strips mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A surface-resistant and wear-resistant stainless steel strip structure includes a stainless steel substrate layer, wherein a composite coating layer and a wear-resistant coating are respectively provided on the top and bottom surfaces of the stainless steel substrate layer.

[0006] The top and bottom surfaces of the stainless steel substrate layer are provided with anti-peeling seats to disperse contact stress and reduce material peeling.

[0007] The bottom surface of the composite coating layer is provided with an anti-peeling sheet, the surface of the anti-peeling sheet is provided with a metal coating layer, the top surface of the wear-resistant coating is provided with a connecting sheet, and the surface of the connecting sheet is provided with a ceramic coating made of laser-clad ceramic particles.

[0008] The top surface of the connecting piece and the bottom surface of the anti-peeling piece are both provided with anti-peeling grooves that are adapted to the size of the anti-peeling seat and engage in a snap-fit ​​manner.

[0009] Preferably, the stainless steel substrate layer has several sets of uniformly and equidistantly arranged prestressed tensile internal wires installed inside.

[0010] Preferably, the thickness of the stainless steel substrate layer is 0.5-3 mm, and the diameter of the prestressed tensile inner wire is one-fifth to one-third of that of the stainless steel substrate layer.

[0011] Preferably, both the anti-peeling seat and the anti-peeling groove have isosceles trapezoidal cross sections.

[0012] Preferably, the metal coating layer is a chromium-plated film or a chemically plated nickel film, with a thickness of 50-200 μm.

[0013] Preferably, the thickness of the ceramic coating is 0.1-0.5 mm.

[0014] Preferably, the outer wall of the ceramic coating is provided with smooth anti-slip protrusions, which are made of the same material as the ceramic coating and are integrally formed.

[0015] Compared with existing technologies, the beneficial effects of this utility model are:

[0016] In this scratch-resistant and wear-resistant stainless steel strip structure, a stainless steel substrate layer serves as the basic structure, providing strength support. A composite coating layer and a wear-resistant coating are respectively applied to its top and bottom surfaces, and these three components are integrally molded to enhance overall stability. Anti-peeling seats on the top and bottom surfaces of the stainless steel substrate layer, in conjunction with anti-peeling plates on the bottom surface of the composite coating layer and anti-peeling grooves on the connecting plates on the top surface of the wear-resistant coating, can disperse contact stress and reduce material peeling. The metal coating layer on the surface of the anti-peeling plate on the bottom surface of the composite coating layer enhances corrosion resistance and wear resistance. The surface of the wear-resistant coating connecting plates uses a ceramic coating of laser-clad ceramic particles, further improving the surface's scratch and wear resistance. This results in a stainless steel strip structure with excellent scratch and wear resistance, anti-peeling properties, and overall stability.

[0017] In this surface-resistant and wear-resistant stainless steel strip structure, several sets of uniformly and equidistantly arranged prestressed tensile inner wires are installed inside the stainless steel substrate layer. The thickness of the stainless steel substrate layer is 0.5-3mm, and the diameter of the prestressed tensile inner wire is one-fifth to one-third of that of the stainless steel substrate layer. This significantly enhances the tensile strength of the stainless steel strip, enabling it to better withstand external pulling forces without easily deforming or breaking.

[0018] In this surface-resistant and wear-resistant stainless steel strip structure, the outer wall of the ceramic coating is provided with smooth anti-slip protrusions. The anti-slip protrusions are made of the same material as the ceramic coating and are integrally formed, which increases the friction between the stainless steel strip and the contact object during use, making it less prone to slipping, while not affecting its surface anti-slip and wear-resistant properties.

[0028] A stainless steel strip structure with a scratch-resistant and wear-resistant surface, such as Figures 1-3As shown, the structure includes a stainless steel substrate layer 10, with a composite coating layer 20 and a wear-resistant coating 30 respectively disposed on the top and bottom surfaces of the stainless steel substrate layer 10, all three being integrally formed. The top and bottom surfaces of the stainless steel substrate layer 10 are provided with anti-peeling seats 12 for dispersing contact stress and reducing material peeling. The bottom surface of the composite coating layer 20 is provided with an anti-peeling piece 21, the surface of which is provided with a metal coating layer 22. The top surface of the wear-resistant coating 30 is provided with a connecting piece 31, the surface of which is provided with a ceramic coating 32 using laser-clad ceramic particles. Both the top surface of the connecting piece 31 and the bottom surface of the anti-peeling piece 21 are provided with anti-peeling grooves 23 that are adapted to the size of the anti-peeling seat 12 and engage with it. The stainless steel substrate layer 10 serves as... The basic structure provides strength support; the top and bottom surfaces are respectively provided with a composite coating layer 20 and a wear-resistant coating 30, and the three are integrally formed to enhance overall stability; the anti-peeling seats 12 on the top and bottom surfaces of the stainless steel substrate layer 10, together with the anti-peeling sheet 21 on the bottom surface of the composite coating layer 20 and the anti-peeling groove 23 on the connecting piece 31 on the top surface of the wear-resistant coating 30, can disperse contact stress and reduce material peeling; the metal coating layer 22 on the surface of the anti-peeling sheet 21 on the bottom surface of the composite coating layer 20 enhances corrosion resistance and wear resistance; the surface of the connecting piece 31 of the wear-resistant coating 30 is coated with a ceramic coating 32 of laser-fused ceramic particles, which further improves the surface's scratch and wear resistance, making the stainless steel strip structure have excellent scratch and wear resistance, anti-peeling and overall stability.

[0029] Furthermore, several sets of uniformly and equidistantly arranged prestressed tensile inner wires 11 are installed inside the stainless steel substrate layer 10. The thickness of the stainless steel substrate layer 10 is 0.5-3mm, and the diameter of the prestressed tensile inner wires 11 is one-fifth to one-third of the stainless steel substrate layer 10, which significantly enhances the tensile performance of the stainless steel strip, enabling it to better withstand external force and avoid deformation or breakage.

[0030] It is worth noting that both the anti-peeling seat 12 and the anti-peeling groove 23 have isosceles trapezoidal cross sections, which makes them fit together more tightly and stably, effectively dispersing contact stress, reducing material peeling, and improving the reliability of the stainless steel strip structure.

[0031] Specifically, the metal coating layer 22 is a chromium-plated film layer or a chemically plated nickel film layer with a thickness of 50-200μm, which gives the composite coating layer 20 good anti-corrosion, wear resistance and aesthetic properties, and extends the service life of the stainless steel strip.

[0032] The ceramic coating 32 has a thickness of 0.1-0.5mm, which gives the stainless steel strip surface high hardness and scratch and wear resistance, effectively resisting external scratches.

[0033] In addition, the outer wall of the ceramic coating 32 is provided with smooth anti-slip protrusions 33. The anti-slip protrusions 33 are made of the same material as the ceramic coating 32 and are integrally formed, which increases the friction between the stainless steel strip and the contact object during use, making it less prone to slipping, while not affecting its surface anti-scratch and wear-resistant properties.

[0034] The working principle of this scratch-resistant and wear-resistant stainless steel strip structure:

[0035] In use, the stainless steel substrate layer 10 serves as the main structure, providing basic strength and toughness for the whole. The internal prestressed tensile inner wire 11 enhances its tensile performance, ensuring that it is not easily deformed under stress. The anti-peeling seat 12 on the stainless steel substrate layer 10 is engaged with the anti-peeling groove 23 on the bottom surface of the anti-peeling sheet 21 of the composite coating layer 20 and the top surface of the connecting piece 31 of the wear-resistant coating 30, ensuring a tight connection between the layers, effectively dispersing stress, and preventing material peeling. The metal coating layer 22 protects the stainless steel strip from corrosion. The ceramic coating 32 of the wear-resistant coating 30 has high hardness and can resist scratches. During installation, hard objects should be prevented from impacting and damaging the ceramic coating 32 and the anti-slip protrusions 33.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
