Problems solved by technology

Patterns of various colors can be formed by spraying, but it is difficult to form fine patterns due to the phenomenon of uneven coating thickness and paint accumulation due to spraying, and the coating formed by this method has poor wear resistance
Chemical treatment, laser engraving or CNC milling are difficult to make the pattern into color, and coloring treatment such as spraying is still required to make the pattern appear in various colors, so there is also the problem of poor wear resistance of the coating
Using ink to cover the surface of the stainless steel substrate, and then vacuum coating the unshielded surface of the stainless steel substrate to form a pattern still has certain defects: the ink used for shielding is easy to contaminate the unshielded surface, resulting in a decrease in the adhesion of the vacuum coating layer

Embodiment Construction

[0024] see figure 1 As shown, a stainless steel product 10 according to a preferred embodiment of the present invention includes a stainless steel substrate 11 on which a textured portion 113 and a non-patterned portion 115 are formed.

[0025] The patterned part 113 is formed with a vacuum coating layer 13, and the vacuum coating layer 13 is formed as a preset decorative pattern, text or trademark. The vacuum coating layer 13 can be a film layer containing chromium element such as chromium carbide (CrC) layer, chromium nitride (CrN) layer or chromium carbonitride (CrCN) layer. The vacuum coating layer 13 has good hardness and wear resistance. The thickness of the vacuum coating layer 13 is 0.8-3 μm. In this example, the vacuum coating layer 13 appears black.

[0026] In this example, the 60° angle glossiness of the surface of the non-patterned portion 115 is 220-240, showing a highlight effect.

[0027] The method for manufacturing the stainless steel product 10 according...

Abstract

The invention provides a stainless steel product comprising a stainless steel substrate, wherein a pattern part and a non-pattern part are formed on the stainless steel substrate; the pattern part is composed of a vacuum coating layer which is a chromium element contained coating layer; and the non-pattern layer has a polished appearance effect. The invention also provides a manufacturing method of the stainless steel product.

Description

technical field [0001] The invention relates to a stainless steel product and a manufacturing method thereof. Background technique [0002] Due to its good wear resistance, stability, impact resistance and high hardness, stainless steel is widely used in electronic devices (such as mobile phones), auto parts and architectural decorations. The existing methods are generally to make various decorative patterns on the surface of the stainless steel substrate by surface treatment such as painting, chemical treatment, laser engraving or CNC milling, so as to obtain a better appearance effect for the stainless steel substrate. Patterns of various colors can be formed by spraying, but it is difficult to form fine patterns due to the phenomenon of uneven coating thickness and paint accumulation due to spraying, and the coating formed by this method has poor wear resistance. Chemical treatment, laser engraving or CNC milling and other methods are difficult to make the pattern into c...
