自润滑高温复合材料美国航天航空局Ｌｅｗｉｓ研究中心新近开发成功一种能在很宽的温度范围内具有自润滑作用的高温复合材料－ＥＸ２１２。它是由碳化铬粉末、镍基粘结剂（７０％）、银粉（１５％）以及氟化钡与氟化钙的共晶混合物（１５％），通过粉末冶金法制成。这种复...
Lubrication of high-temperature composite materials NASA Lewis Research Center recently developed a high temperature composite material with a self-lubricating effect over a wide temperature range - EX212. It is made by powder metallurgy from chromium carbide powder, nickel based binder (70%), silver powder (15%) and a eutectic mixture of barium fluoride and calcium fluoride (15%). This complex ...
