Too surface treatment method

Abstract

The invention relates to a surface treatment method for a tool. The method comprises the following steps of: pretreating the tool; and compounding a diffusion layer on the tool, wherein the compound diffusion layer is a metal ion layer into which titanium ions or aluminum ions are injected, and can be a carbon diffusion layer, a nitrogen diffusion layer or a carbon-nitrogen co-diffusion layer. Layer diffusion treatment is performed on the tool, so that the physical and chemical performance of the surface is changed, the strength of the tool is enhanced remarkably under the condition of not lowering other performance, and excellent comprehensive performance is ensured.

Description

technical field

[0001] The invention relates to a surface treatment method, in particular to a tool surface treatment method. Background technique

[0002] In daily life, knives are indispensable. In order to prevent corrosion, a large number of knives are made of stainless steel. However, the strength of stainless steel itself is low and its mechanical properties are poor. In the prior art, heat treatment is performed to improve the strength, but the corrosion resistance deteriorates. , cannot meet the usage requirements. Contents of the invention

[0003] The invention aims at the deficiencies of the prior art, and provides a cutting tool with good mechanical performance and corrosion resistance and a surface treatment method thereof.

[0004] The present invention realizes through following technical scheme:

[0005] A tool surface treatment method comprises the following steps: pretreating the tool; and then compounding a permeable layer on the tool.
