The phenomena connected with friction and wear processes are the most frequent cause of engineering components damage. The damage of even only one component results many times in the necessity of the whole engine plant shutdown (in the worse cause in its breakdown), what evokes the owner's minor or larger losses. That is the reason, why in last years the task of the service life prolongation (wear decrease) comes to foreground. There are several possibilities to solve this problem. The use of surfacing technology - making of special wear resistant overlay on the functional part surface - is one of them. But the manufacturers and sellers do not give the wear resistance information of their overlay materials. In the practice the optimum selection of surfacing could be based on the own experiments or on the published tests results. This paper contains the laboratory wear resistance test results of selected hardfacing materials. The tests were realized at the modified pin abrasion testing machine with abrasive cloth. From the test evaluation it follows that the overlays wear resistance is a complex material property and it is not possible to evaluate it only on the basis of partial information about their chemical composition, metallographic structure or mechanical properties. On the basis of the test results it is possible to stay, that at present the adequate number of first-rate overlay materials are on the market.
