Reciprocating Triboligical Behavior of PA1010 Filled with ZnOw
The friction and wear behavior of nylon1010 composites filled with different proportions of ZnOw in reciprocating sliding against GCr15 steel ball under dry friction condition were studied. The worn surface and wear particles were then examined with SEM. The elastic modulus, nano-hardness and ball indentation hardness of composites increased with the content of ZnOw. The coefficients of friction of composites decreased lightly, which changed from 0.36 and 0.26 of nylon matrix to 0.30 and 0.22 of composites at 0.04 m/s and 0.08m/s sliding velocity, respectively. The anti-wear property of composites was improved with large extent. The typical wear mechanism of nylon matrix is adhesion and micro-melting. However, peeling of surface layer appears owing to fatigue for composites. Roll-shaped wear debris were produced for pure nylon, while flake-like debris for nylon composites.
