Product Description
The hard chromium plating layer has excellent characteristics which combine the original properties of chromium metal with the advantages of erectro-deposits. The main features of hard chromium plating are as follows:
1. Extermely high hardness of HmV (Micro Vickers)
800 to 1100 (cf. gray cast iron 220 to 270)
2. High melting point of approx. 1800℃ (cf. cast iron 1200℃ )
3. Good thermal conductivity and corrosion resistance.
4. Low friction factor and excellent wear resistance. Such features are very effective in preventing piston ring wear.
