Ускоренные испыта ния материалов на изнашивание

The methodology of accelerated tests of materials for wear in a pair of the disc-plane and the disk-to-disk is considered. A distinctive feature of the proposed method of testing is the constancy of the contact area of the elements in the friction zone. A design of a portable installation developed to implement considered testing methodology is described. The results of comparative tests of steel samples with different carbon content hardened by electromechanical treatment for wear are presented. It is shown that the results of testing for wear resistance obtained according to the proposed procedure match with the data of standard testing method, the difference being no more than 9%. The duration of each sample testing is reduced ten times.
