3. Wear rate in applications

3.1 Wear rate and service life

The loss of surface layer thickness or linear wear Δh over time Δt (Δh/Δt) is constant in the stationary wear regime. This can be expressed in another way: the loss of thickness of a surface layer Δh is the quotient of the wear volume ΔV and the contact area A. This gives the formula (5) :

Δh=kVFN ΔdA
