使用することができない。[Problems to be Solved by the Invention] In the conventional example described above, the surface hardness of Ni plating and Zn plating is about HV400, and there is a problem in wear resistance. Cr plating has a durability of about HV800, but it is not suitable for mass production because the plating is unevenly applied to parts for electroplating.
Even Ni-P plating has a low wear resistance of HV400 or less, which is a problem. In addition, if heat treatment is performed at around 400℃ after Ni-P plating, the HV will improve to about 800, but
In that case, the original magnetic properties of the material deteriorate, so it cannot be used.
