Properties multilayer overlay materials

Abstract

At present a great number of machines and mechanisms of various types are used in the industrial production. Often the whole operation depends on the trouble-free service of single parts and many times a minor defect may conduce to the shutdown of the whole production line or of the other operation. From this reason the uncaused losses of many thousands often occur. One of the very effective measures of the wear resistance increase is surfacing of functional surfaces using the suitable overlay material. Used overlay materials have various properties. In the paper the chosen overlay materials are compared by means of the abrasive wear determination. The wear resistance was tested using the laboratory apparatus with bonded abrasive particles (according to CSN 01 5084).
