Abstract

The invention discloses a low-cost titanium alloy anti-oxidation annealing method, and belongs to the technical field of titanium alloy heat treatment so as to solve the problem that an existing titanium alloy is prone to being oxidized in the annealing process. The titanium alloy anti-oxidation annealing method comprises the steps that a titanium alloy bar with a protective coating is placed into a tubular annealing furnace, the tubular annealing furnace is filled with argon, then the temperature of the tubular annealing furnace is set at an annealing temperature, and annealing is carried out. According to the low-cost titanium alloy anti-oxidation annealing method, firstly, epoxy polyhedral silsesquioxane is used for carrying out chemical modification on methyl phenyl organic silicon resin, then the organic silicon resin serves as a film-forming base material of a coating, the protective coating is formed on the surface of the titanium alloy bar, annealing is carried out in the tubular furnace under the argon atmosphere, dual protection of argon and the protective coating is formed, the problem of oxidation of the titanium alloy in the annealing process is avoided, the titanium alloy bar can be subjected to annealing treatment at a high temperature, and the annealing cost is low.

Description

technical field [0001] The invention belongs to the technical field of titanium alloy heat treatment, and in particular relates to a low-cost titanium alloy anti-oxidation annealing method. Background technique [0002] In recent years, titanium alloys have been widely used in aerospace, medical chemical industry, navigation, nuclear power and other fields. These industries have extremely high requirements on the quality of titanium alloys. The annealing process is an important step in the production of titanium alloy products. The reaction of titanium materials in the air usually reacts with three non-metallic elements such as oxygen, nitrogen and hydrogen. Their reaction process is closely related to temperature, which will lead to a significant decrease in the mechanical properties of titanium alloys, and at high temperatures In the environment, titanium alloy is extremely easy to oxidize. In order to solve this problem, vacuum furnace annealing technology and nitrogen pr...
