C06 めっき皮膜の超精密切削加工に関する基礎的検討(OS11 超精密加工(2)) C06 Study on Ultra Precision Cutting of plating materials

Plated alloy have been attempted to improve heat and wear resistance and insulation properties of machine parts. Particularly alloy of nickel and phosphorus(Ni-P) have benefit for the mold of glass or plastic lens which have property of highly heat and wear resistance. Ordinarily the plated Ni-P is made by a process of electroless plating. In this study, I used the plated Ni-P which made by a process of electroplating. In this process, a plated alloy can contain more amount of phosphorus. Single crystal diamond turning experiment for the cylindrical end face plated electrolytic Ni-P was carried out, and analyzed the potential of ultra precision cutting of electrolytic Ni-P and the effect of amount of content phosphorous. It was turned out that Electrolytic Ni-P have potentiality to be worked as electroless Ni-P, and to improve the surface roughness by the increase of the amount of content phosphorous.
