Description

technical field

[0001] The invention belongs to the technical field of ablation-resistant materials, in particular to an ablation-resistant polyphenylene sulfide composite material and a preparation method thereof. Background technique

[0002] Micro-arc oxidation, also known as micro-plasma oxidation and plasma electrolytic oxidation, is a new technology for in-situ growth of ceramic films on the surfaces of aluminum, magnesium, titanium and other metals. In the process of micro-arc oxidation, the metal surface relies on arc discharge to generate instantaneous high temperature and high pressure, and the base metal is directly oxidized and sintered into an oxide ceramic film layer. Features such as high temperature shock, wear resistance and electrical insulation. The technology has the characteristics of simple operation, no pollution and high efficiency, and has broad application prospects in the fields of aerospace, electronics and machinery.
