Adhesive Wear Rate Between Two Metals



Purpose of calculation:
Determine the adhesive wear rate of two metals.
This calculation is featured as a case study.
Calculation Reference
1. Wear Coefficients - Metals Section IV of 10, E. Rabinowicz.
2. Fundamentals of Machine Component design, Juvinall
Calculation Validation
Check against calculation in Ref. 2
Calculation Procedure
Compatibility of Various Metal combinations (increasing compatibility increasing tendency to weld and increasing wear rate)
  • Indium
  • Lead
  • Tin
  • Cadmium
  • Magnesium
  • Zinc
  • Aluminium
  • Silver
  • Gold
  • Copper
  • Titanium
  • Zirconium
  • Platinum
  • Niobium
  • Iron
  • Nickel
  • Cobalt
  • Chromium
  • Molybdenum
  • Tungsten
Wear Coefficient Upper Limit (Of softer material)
Wear Coefficient Lower Limit (of softer material)
Estimated Wear Coefficient (set between limits or calculate average)
Surface Hardness (note. Brinell, Vickers and Knopp hardness values are in kg/mm²)
Contact Pressure
Sliding Distance (often calculated as a velocity x time)
Wear Depth
