Abstract

The invention relates to a titanium alloy sealing process. The titanium alloy sealing process comprises the following steps of (1) assembling a metalized and nickel-plated ceramic insulator, a lead and a titanium alloy shell together; (2) placing welding flux in the sealing position; (3) putting an assembled product into a vacuum furnace; (4) adjusting the temperature of the vacuum furnace to 800-810 DEG C for sealing, and enabling the heat preservation time to be 10 minutes; and (5) taking out the product and checking the welding quality. Compared with the prior art, the titanium alloy sealing process has the beneficial technical effects that the titanium alloy sealing process technically solves the problem that titanium alloy sealing crystal grains become large; surface treatment caused by oxidation discoloration is avoided, and the production efficiency is improved; and the sealing performance and the insulating performance among a titanium alloy, the insulator and the lead are improved, and the titanium alloy sealing process is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of titanium alloy sealing, in particular to a titanium alloy sealing process. Background technique [0002] With the continuous improvement of military product technical requirements, product performance standards are becoming more and more stringent. At present, most of the peers use glass sealing when sealing titanium alloys, because the sealing temperature of glass is 999~1100 ° C, which exceeds the standard of titanium alloys. The phase transition temperature causes the grains of the titanium alloy to become larger and the mechanical properties to decrease after high temperature sealing. Contents of the invention [0003] The main purpose of the present invention is to solve the above deficiencies and provide a method in the field of titanium alloy and insulating material packaging to solve the problem of mechanical performance degradation caused by the enlarging of grains of titanium alloy products af...
