摘要

46.5~57 includes Al, Cu 20~25.5, 12~15 Fe, Si in 8~15 atomic%, and the coating layer is present having a quasicrystalline structure or similar, preferably, further comprises a B of 1% or less . High hardness, it is possible to obtain a composite coating with a good wear and friction properties. ; Coating, mesophase
