Abstract
The abrasive wear, fatigue, and tensile properties of polyamide 6 (PA6) dispersed with titanium carbide particles, aluminum borate whiskers, and vapor-grown carbon fibers were determined. Moreover, the correlation between them was investigated using the equation Ws=(gf)/(kH), where Ws is the wear rate, g is the shape factor of the abrasive particles, f is the fracture probability, k is a constant, and H is the microhardness. The value of 1/f represents the number of deformation cycles imposed by the abrasive particles until a local fracture occurs at the material surface. At a low sliding velocity, a correlation was observed between 1/f and the low stress fatigue life. At a high sliding velocity, f approached unity and a correlation was found between the wear rate and the tensile fracture work, which is in agreement with the Ratner-Lancaster plot.
