How Plastics Wear Against Metals
Testing Thermoplastic Composites against Steel
How do plastics wear against metals? Tests mating thermoplastic composites and AINSI 1141 cold-rolled steel counter-faces were done. The highest composite wear factors (greatest wear) resulted with the smoothest range (8-12 µin.) of metal surface finishes. Contrary to what might be expected intuitively, this result is attributed to the adhesion-and-deformation friction mechanism of metal/plastic combinations. The 12 to 16 µin. range yielded the lowest wear factors. The 50 to 70 µin. … Read more
