Define Abrasion Resistance: Complete Material Testing Guide - Product

Quick Answer

• Abrasion resistance is a material's ability to withstand surface wear from friction, scratching, and rubbing forces without significant degradation
• Measured through standardized tests like ASTM G65, Taber Abraser, and sandblasting methods with numerical ratings
• Ceramics and hardened metals typically offer superior abrasion resistance compared to polymers and soft materials
• Critical for industrial applications including mining equipment, automotive parts, and protective coatings
• Differing from scratch resistance, abrasion resistance involves cumulative wear over extended contact periods

Understanding Abrasion Resistance vs Related Material Properties
