Achievements in research on robber wear by the present aulhor and his group over the past ten years arc summarized briefly Tbcsc results include mechanisnls and wear equations for dry and wctabrasion, basic features and wear nlechanism of oily abrasion, tbeory of dry abrasion by a line comtact, physical processes and surface mecbanocbcmical effects of abrasive erosion. They are not only significant in the context of rubber tlibokrgy bu; are also valuable for extending tile working life of rubber components

【期刊论文】Investigation of abrasive erosion of polymers
张嗣伟, S.W. ZHANG, WANG DEGUO, YIN WEIHUA
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.

【期刊论文】Energy theory of rubber abrasion by a line contact
张嗣伟, S.W, Zhang, and Zhaochun Yang
Trbology btternational Vol. 30. No.12, pp. 839-843. 1997,-0001,():

A new energy theory of rubber abrasion by a line contact hasbeen set up through analyzing the energy distribution andconversion during the abrasion process, corresponding theoreticalwear equation of rubber abrasion by a line contact in unsteadystate has been derived. This energy theory, which is animprovement on the previous theory of rubber abrasion by a linecontact, can be used to clarify the phenomena and processes ofthe rubber abrasion.

【期刊论文】Advances in studies on rubber abrasion*
张嗣伟, S.W. Zhang**
Proceedings of Japan Internationat Tribology Conference nagoya, 1990,-0001,():
-1年11月30日
This article is a brief survey of some of the important processes involved in the abrasive wear of rubber. The progress in understanding rubber abrasion during the past decade is reviewed under three headings of dry abrasion (single point contact abrasion, line contact abrasion and multiple contact abrasion), oily abrasion and wet abrasion (two body and three body abrasion)
