The effect of ZrO2 addition on the polarization behavior of Cr-ZrO2 composite coating

Hard chromium coating is mainly used to improve the surface performance of pistons, brake disks and gears. In the future, better abrasion resistance and better corrosion resistance of hard Cr coating are demanded. Co-deposition of ceramic particles in Cr coating improved these characteristics. The C...
