Abstract

Composite coatings based on inorganic binders have been developed for corrosion protection of aircraft engine parts, for which stability at elevated operation temperatures is required and increased demands are placed on safety and durability of aircraft nodes. There is a problem in producing binders that lies in the necessity to introduce hexavalent chromium compounds, which are compounds of the first hazard class, as inhibitors. To solve this problem, the engineers follow the path of increasing the binder pH and coating isolating layers, as well as applying nontoxic inhibitors, which allows one to coat the composite material on a metal substrate to exclude hydrogen saturation of high-strength steel.

基于无机磷酸盐的复合涂料（综述）

摘要

已经开发了基于无机粘合剂的复合涂层以保护飞机发动机部件，为此需要在升高的操作温度下的稳定性，并且对飞机节点的安全性和耐久性提出了更高的要求。生产粘合剂的问题在于必须引入六价铬化合物作为抑制剂，所述六价铬化合物是第一类危险物质。为了解决这个问题，工程师们沿着增加粘合剂pH值和涂覆隔离层以及应用无毒抑制剂的方法，允许人们将复合材料涂覆在金属基材上，以排除高强度钢的氢饱和。
