If it exceeds 0.2μ, the plating layer will fall off quickly and
If it is less than that, the wear resistance will be poor.

乱し高速性に乏しいという欠点がある。Furthermore, the surface roughness of the contact and sliding surface of the traveler,
Although the PaO was reduced to less than 2μ by polishing, the surface roughness of the plating without polishing exceeded 0.2μ, presenting a surface with poor smoothness, which disturbed the traveling of the traveler and hindered high-speed performance. It has the disadvantage of being scarce.

を延長させる利点がある。The hard particles to be eutectoided into the composite plating layer include silicon carbide, tungsten carbide, boron nitride, aluminum oxide, etc., but these have high hardness, high chemical resistance, and high wear resistance.
Furthermore, silicon carbide is the best because it has good thermal conductivity and can easily dissipate the frictional heat generated when the traveler runs, which has the advantage of extending the life of the traveler.
