WebHard chrome has a very low coefficient of friction. Applying a surface finish, like hard chrome, would greatly reduce friction, therefore increasing the service life and performance of the parts. Mathematically, μ = F/N, where F is the frictional force and N is the normal force. The following table shows comparable materials and surface finishes.
