南京航空学院材料科学系研制成功高温耐磨Ni—Sic复合镀层技术,可使金属零件的耐磨性能成倍提高。复合镀层是用电镀或化学镀的方法,使固体微粒与金属离子在水溶液中一起沉积在零件表面上的一种新技术。当这些微粒均匀地嵌入金属基架后,形成的复合镀层具有抗 Nanjing Aeronautical Institute of Materials Science successfully developed high-temperature wear-resistant Ni-Sic composite coating technology, the wear resistance of metal parts can be doubled. Composite coating is the use of plating or electroless plating method, the solid particles and metal ions deposited in aqueous solution with a new technology in the surface. When these particles are uniformly embedded in the metal pedestal, the resulting composite coating has resistance
