Abstract
Experimental studies of wear resistance of deposited metal, produced with feeding of nanooxides to weld pool, are of interest, when searching for new methods to guarantee the high wear resistance of deposited metal for items exposed to friction in service. The paper presents the results of testing wear resistance of deposited metal of 40Kh13, 25KhG2S, 300Kh28M type, modified by aluminium, titanium and silicon nanooxides through the weld pool with different schemes of their feeding. It is shown that nanooxide feeding to weld pool leads to a noticeable increase of deposited metal wear resistance. 13 Ref., 8 Figures.
