Material for high-mechanical-strength parts

Abstract

The invention discloses a material for high-mechanical-strength parts. A titanium alloy steel plate and an aluminum alloy coating are matched and experimented again, a large number of experiments prove that by means of matching, the mechanical strength, the anti-fatigue strength and the shock resistance of the prepared metal material can reach the optimal state, the using performance of the metal material is improved greatly, and texture demands for manufacturing the parts of automobiles, the aerospace parts and the like are met. By arranging a curved groove with the V-shaped cross section, an aluminum alloy electro-deposition coating and the titanium alloy steel plate can be combined into one more firmly, and the shock resistance and the anti-fatigue strength can be improved more superiorly. In addition, by sequentially arranging the aluminum alloy electro-deposition coating and an aluminum alloy PVD gas phase physical deposition coating, the effect of coating combination can be better; and finally pyrolysis is set, an oxidation film can be formed on the surface of the aluminum alloy deposition coating better, and the comprehensive performance of the metal material is enhanced.

Description

technical field [0001] The invention belongs to the technical field of mechanical material manufacturing, in particular to a material for parts with high mechanical strength, and belongs to the technical field of material engineering. Background technique [0002] In automotive, aerospace and other technical fields, the mechanical strength requirements of metal materials are quite high, and it is also necessary to make them have strong impact resistance and good corrosion resistance. With the continuous emergence of new materials, titanium alloys have gradually attracted people's attention. However, due to the advantages of low density, high strength and high temperature resistance, titanium alloys have been widely used in aerospace fields. However, titanium alloys are prone to wear and react with oxygen in the atmosphere at high temperatures, which limits the full utilization of titanium alloys. In order to use titanium alloys for special purposes, the surface coating trea...
