Wear Rate (Archard's Wear Equation) Calculator

Wear Volume (wear rate) (V):

Wear Coefficient (k):

Normal force between surfaces (F_n):

Sliding distance (L):

Hardness of the material (H):

How This Is Calculated

$$ V = \frac{k \cdot F_n \cdot L}{H} $$ where:

V = Wear Volume (wear rate) (m³)

k = Wear Coefficient (Dimensioness)

F_n = Normal force (N)

L = Sliding distance (m)

H = Hardness of the material (Pa)

Assumptions

The wear process has reached a steady state condition.
Contact pressure is uniform.
The material is homogeneous.
There is no adhesive wear.
No surface coating effects are present.
