【摘要】：基于钛合金优良的性能,已广泛应用于航空、航天、化工、船舶等领域,但其表面的耐磨、耐蚀性等还不能满足某些关键零部件的要求。微弧氧化技术是一种在铝、镁、钛等有色金属及其合金表面原位生长氧化膜的新技术,利用该技术制备的氧化膜具有耐腐蚀、耐磨、硬度高和电绝缘等优良特性。本文阐述了微弧氧化的基本原理,系统研究了船用钛合金微弧氧化的电源参数、电解液配方、工艺等,并明确了氧化膜层质量检测项目。
[Abstract]:Based on the excellent properties of titanium alloy, it has been widely used in aviation, aerospace, chemical industry, ship and other fields, but its surface wear resistance, corrosion resistance and so on can not meet the requirements of some key parts. Micro-arc oxidation technology is a new technology for in-situ growth of oxidation film on the surface of non-ferrous metals such as aluminum, magnesium, titanium and its alloys. The oxide film prepared by this technology has excellent properties such as corrosion resistance, wear resistance, high hardness and electrical insulation. In this paper, the basic principle of micro-arc oxidation is described, the power parameters, electrolyte formula and process of micro-arc oxidation of marine titanium alloy are systematically studied, and the testing items of oxidation film quality are defined.
