FATIGUE- RESISTANT COATING FOR METAL FORMING MEMBERS

摘要

A composite coating for a metal forming member includes a first layer disposed on said metal forming member. The first layer includes chromium nitride doped with at least one dopant such as tungsten. A second layer is disposed atop said first layer, said second layer including a lubricious material having a coefficient of friction of less than or equal to 0.2 as measured against low alloy steel.
