Description

technical field [0001] The invention relates to a scanning laser-assisted micro-arc oxidation device and a process method thereof. Background technique [0002] In recent years, my country's aerospace industry has achieved rapid development. Due to the particularity of the use environment, aerospace equipment needs to use a large number of special engineering materials. This has prompted great progress in the research of aerospace materials in our country, and one of the research focuses is the lightweight of aerospace materials. After long-term production practice and scientific research, people have gradually strengthened some metal materials by adding alloy elements and using heat treatment to obtain a series of light alloys. Some light alloys are light alloys with excellent mechanical properties and high specific stiffness. , can meet the lightweight requirements of the aerospace field, but some light alloys have low surface hardness and poor corrosion resistance, which...

Problems solved by technology

Micro-arc oxidation technology still faces the following problems in practical application: (1) high energy consumption, limited by the design and manufacturing level of ultra-high-power power supply, resulting in the inability to handle super-large workpieces; (2) local repairs on site are difficult to achieve; (3) ) It is extremely difficult to process workpieces with different film performance requirements in each area; (4) Micro-arc oxidation treatment will reduce the fatigue life of the substrate

These problems have become a major bottleneck restricting the further promotion and application of micro-arc oxidation technology in aerospace and other high-end equipment
