Tin coating:
Improve surface hardness and wear resistance;
Reduced coefficient of friction;
Improving heat resistance ;

Acid treatment:
Nitrogen treatment can improve the performance of wire tapping, it is because increasing the hardness of wire tapping, enhances wear resistance increases heat resistance, make wire tapping of high temperature performance better.By nitriding treatment, about wire tapping the surface hardness up to 1300HV, about maternal hardness 64HRC (=870HV) of 1.5 times.
