Problems solved by technology

[0005] In order to solve the problems of difficult control of thermal deformation, quality stability and low yield rate during the nitriding treatment of the surface of titanium alloy parts, the present invention proposes a nitriding treatment method for the surface of titanium alloy parts, which is different from the current surface nitriding treatment of titanium alloy parts. Compared with the nitrogen treatment method, the present invention can effectively solve the thermal deformation problem of the existing titanium alloy parts surface nitriding treatment, thereby significantly improving the quality stability and product yield of the titanium alloy parts surface nitriding treatment

Abstract

The invention relates to a titanium alloy part surface nitriding treatment method. The method comprises the steps of (1) preheating a titanium alloy part raw material; (2) roughly machining the preheated part raw material to obtain a semi-finished part, specifically, the semi-finished part is provided with a to-be-nitrided surface; (3) carrying out the surface nitriding treatment on the to-be-nitrided surface of the semi-finished product part to obtain a nitrided part; and (4) carrying out finish machining on the nitrided part to obtain a finished part. By means of the titanium alloy part surface nitriding treatment method, the problems that the thermal deformation is difficult to control, the quality stability is poor and the yield is low in an existing titanium alloy part surface nitriding treatment process are solved, so that the quality stability and product yield of the titanium alloy part surface nitriding treatment are remarkably improved, the titanium alloy nitriding cost is reduced, and the wide engineering application of the titanium alloy part surface nitriding treatment process is favourably and greatly promoted.

Description

technical field [0001] The invention belongs to the technical field of metal heat treatment and surface treatment, and in particular relates to a method for nitriding the surface of metal parts, in particular to a method for nitriding the surface of titanium alloy parts. Background technique [0002] Titanium alloys have outstanding features such as low density, high specific strength, good thermal stability, and good corrosion resistance, and are widely used in military and civilian fields such as aviation, aerospace, marine, chemical, and medical. However, titanium alloy materials also have low hardness, high and unstable friction coefficient, relatively active chemical properties, flammable high-temperature and high-speed friction (technical titanium fire "fire", poor wear resistance, etc., and have serious adhesive wear and microscopic wear. Sensitivity to dynamic wear greatly limits the wide application of titanium alloy parts. For example, in the aerospace industry, ...
