Multilayer ceramic coating for impeding corrosion of sintered NdFeB magnetsK.M.Deen22. Department of Metallurgy and Materials Engineering CEET,University of the Punjab摘 要:coating applied through cathodic arc physical vapour deposition(CAPVD) for protection of sintered NdFeB permanent magnets.The performance of ceramic coating......
and dried at 373 K for 10 h. The double SiC coating was prepared by a two-step technique of pack cementation and low pressure chemical vapor deposition (LPCVD). In the first step, using Si and C as the raw materials, the SiC inner coating was prepared by pack cementation. The powder compositions were as follows: 70%-80% Si, 10%-20% graphite and 5%-15% Al2O3. Al2O3 was used as penetration enhancer......
