Description

Technical Field

[0001] The present application relates to the technical field of tool coatings, and specifically to a TA-C coating for parts products. Background Art

[0002] Tool coating refers to the process of covering the surface of the tool with a layer of special material. This coating can improve the wear resistance, corrosion resistance and cutting performance of the tool. TA-C coating refers to titanium carbide coating, which is a high-performance coating used for tools and other industrial applications.

[0003] The tools used to process aluminum materials need to have TA-C coating on the surface. At present, the existing technology directly covers the coating structure, and the coating structure will wear during the cutting process. The reason is that the TA-C coating is sensitive to impact and peeling. If the TA-C coating is not firmly bonded to the substrate, it will directly cause the coating to peel off or fall off.

[0004] In view of the above-mentioned problems of the prior art, a TA-C coating for parts products is proposed to improve the bonding firmness and bonding strength of the coating, thereby solving the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a TA-C coating for parts products, which has the advantages of firm bonding and long service life.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a TA-C coating for parts products, comprising a substrate tool bearing the coating, a coating structure deposited and formed on the surface of the substrate tool, wherein a bonding layer is bonded between the carbon ion layer and the titanium ion layer;

[0007] A connecting layer is also provided between the coating structure and the substrate tool.

[0008] Furthermore, the coating structure includes a titanium ion layer and a carbon ion layer deposited on the titanium ion layer.

[0009] Furthermore, the thickness of the deposited titanium ion layer is 0.5 micrometers, and the thickness of the carbon ion layer is 1-1.2 micrometers.

[0010] Furthermore, the surface of the substrate tool is configured as a friction surface.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] The TA-C coating for parts products adopts zirconium oxide by setting a connecting layer. The chemical affinity between zirconium oxide and titanium ions is strong, which is conducive to forming a strong bond. Adding a connection to the tool surface can effectively improve the bonding firmness between the TA-C coating and the substrate, ensure the performance and stability of the coating, and at the same time, adding a grinding surface to the surface of the substrate tool can also help enhance the activity of the substrate surface, which is beneficial to the adhesion of the coating, thereby improving the bonding strength between the coating and the substrate tool and effectively improving the service life of the coating.

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] See also Figure 1-3 In this embodiment, a TA-C coating for a parts product includes a substrate tool 1 that carries the coating and a coating structure that is deposited and formed on the surface of the substrate tool 1.

[0019] In this embodiment, the coating structure includes a titanium ion layer 3 and a carbon ion layer 5 deposited on the titanium ion layer 3, wherein the thickness of the deposited film of the titanium ion layer 3 is 0.5 microns, and the thickness of the film of the carbon ion layer 5 is 1-1.2 microns.

[0020] During the coating deposition process, a titanium target is installed on the physical vapor deposition equipment, a high pulse arc power supply is installed, titanium atoms are ionized under the action of the high pulse power supply, the ionization rate of titanium atoms and the state of ion clusters are guaranteed, the generated ions are filtered by a filtering magnetic field, droplets and large ion clusters are filtered out, the nano-particle size of titanium ions deposited on the workpiece is guaranteed, the graphite target is ionized, C atoms are ionized by electric current to produce carbon ions, and a relatively large number of SP3 bond carbon ions are screened by magnetic field filtering to be deposited on the titanium layer in the form of nano-scale crystals.

[0021] It should be noted that a bonding layer 4 is bonded between the carbon ion layer 5 and the titanium ion layer 3 . The bonding layer 4 is titanium carbide, a compound formed by bonding carbon atoms and titanium atoms, and has very high hardness and wear resistance.

[0022] Specifically, carbon atoms and titanium atoms are combined together in a certain ratio to form a compound with a specific crystal structure, which is usually a face-centered cubic crystal structure, in which carbon atoms and titanium atoms are arranged in a certain way to form a stable lattice structure with excellent hardness and wear resistance.

[0023] A connecting layer 2 is also provided between the coating structure and the substrate tool 1 in this embodiment. The connecting layer 2 is formed by depositing a ceramic material of zirconium oxide to form a film structure covering the surface of the substrate tool 1. Since the chemical affinity between titanium ions and zirconium oxide is strong, it is conducive to forming a strong bond, thereby improving the bonding strength of the coating.

[0024] In this embodiment, the surface of the substrate tool 1 is set as a friction surface. Before applying the TA-C coating, the surface of the substrate tool 1 is processed to form a friction surface by sandblasting and grinding to increase the surface roughness of the substrate tool and enhance the mechanical anchoring of the coating and the substrate.

[0025] At the same time, before applying the TA-C coating, the surface of the substrate is precisely cleaned to remove impurities such as oil, dust, etc. to ensure good contact between the coating and the substrate. The surface of the substrate can also be plasma activated to enhance the activity of the substrate surface, which is beneficial to the adhesion of the coating.

[0026] The working principle of the above embodiment is:

[0027] A grinding surface is formed on the surface of the substrate tool 1 by pre-sandblasting and grinding to increase the surface roughness of the substrate tool and enhance the mechanical anchoring of the coating and the substrate. Subsequently, a titanium target is installed on the physical vapor deposition equipment, and a high pulse arc power supply is installed. The titanium atoms are ionized under the action of the high pulse power supply to ensure the ionization rate of the titanium atoms and the state of the ion clusters. The generated ions are filtered by a filtering magnetic field to filter out droplets and large ion clusters to ensure the nano-particle size of the titanium ions deposited on the workpiece, so that the deposited film layer of the titanium ion layer 3 is 0.5 microns. Subsequently, the graphite target is ionized, and C atoms are ionized by electric current to generate carbon ions. A relatively large number of SP3 bond carbon ions are screened by magnetic field filtering to be deposited on the titanium layer in the form of nano-scale crystals. The film thickness of the carbon ion layer 5 is 1-1.5 microns.

[0028] Furthermore, by setting the connecting layer to use zirconium oxide, the chemical affinity between zirconium oxide and titanium ions is strong, which is conducive to forming a strong bond. By adding a connection to the tool surface, the bonding firmness between the TA-C coating and the substrate can be effectively improved, ensuring the performance and stability of the coating. At the same time, adding a grinding surface to the surface of the substrate tool can also help enhance the activity of the substrate surface, which is beneficial to the adhesion of the coating, thereby improving the bonding strength between the coating and the substrate tool and effectively increasing the service life of the coating.
