Abstract

The invention discloses a low-cost titanium alloy anti-oxidation annealing method, belongs to the technical field of titanium alloy heat treatment, and aims to solve the problem that the existing titanium alloy is easily oxidized in the annealing process. And the titanium alloy anti-oxidation annealing method is: put the titanium alloy rod with protective coating in the tubular annealing furnace, then fill the tubular annealing furnace with argon, then set the temperature of the tubular annealing furnace at Annealing temperature, annealing is carried out. And the present invention first utilizes epoxy-based polyhedral silsesquioxane to chemically modify methylphenyl silicone resin, and then uses the silicone resin as the film-forming substrate of the coating to form a layer on the surface of the titanium alloy rod. The protective coating is then annealed in a tube furnace under an argon atmosphere to form a double protection of argon and protective coating, which not only avoids the oxidation of titanium alloys during annealing, but also allows titanium alloy rods to be processed at high temperatures. Annealing treatment, 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...
