Archard Wear Calculator
Sliding-wear volume from load, distance and the wear coefficient.
K spans five orders of magnitude — lubrication, not material choice, is the big lever. Harder surface helps only linearly; a film of oil helps 10,000×.
Formula
Archard Wear Calculator is a free archard wear for design engineers, metallurgists and QA inspectors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Archard Wear Calculator
Sliding-wear volume from load, distance and the wear coefficient. The calculation implements V = K·F·s/H (Archard (1953); tribology handbooks). K spans five orders of magnitude — lubrication, not material choice, is the big lever. Harder surface helps only linearly; a film of oil helps 10,000×.
How to use Archard Wear Calculator
- 1Enter Wear coefficient K (Dry metal 10⁻³–10⁻⁴ · lubricated 10⁻⁶–10⁻⁸).
- 2Enter Normal load in N.
- 3Enter Sliding distance in m.
- 4Enter Hardness of softer surface in GPa (≈ HV/100 GPa; mild steel ~1.5–2).
- 5Read Wear volume instantly — no submit button needed.
- 6Need US units? Flip the SI/Imperial toggle and every field converts.

Frequently asked questions
What formula does the Archard Wear Calculator use?+
It computes V = K·F·s/H, per Archard (1953); tribology handbooks. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
K spans five orders of magnitude — lubrication, not material choice, is the big lever. Harder surface helps only linearly; a film of oil helps 10,000×.
Where do the material property defaults come from?+
Defaults are standard handbook values (ASM, manufacturer datasheets, the cited standard). Always substitute certified values from your material's test certificate for critical work.
Is the Archard Wear Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
