Investigation of abrasive erosion of polymers
JOURNAL OF MAIERIALS SCIENCE 30(1995)4561-4566,-0001,():
rubber, nylon-6 and polytetrafluoroethylene, have been investigated using a specialabrasive erosion test machine designed by the authors. Based upon some observations ofthe abraded surfaces of test samples using scanning electron microscopy (SEM), themechanisms of abrasive erosion for the polymers examined could be summarized asfollows: a mierocutting action of the abrasives with a certain kinetic energy; microdelamination of the surface layer of the materials resulting from initiation andpropagation of microcracks; mechanochernical and thermal decomposition of materials;and surface peeling, resulting from plastic fracture expanded from local plastic deformationof the material. The influence of these factors on the wear rate of the abrasive erosion hasbeen studied, and the relevant wear-rate equations are presented.
