Properties of metal deposited with application of induction method on the parts of working tools of soil-cultivating agricultural machinery during natural aging were studied. Analysis showed that the spare parts stored for 3 to 5 years can undergo natural aging because of various circumstances. This, in its turn, can lead to a change in the properties and structure of both the base and deposited metals. Proceeding from the results of the conducted investigations of the surfaced parts before and after natural aging, it was determined that the structure and microhardness of the deposited metal are practically identical. Results of X-ray microprobe analysis demonstrated no carbon enrichment of deposited metal regions near the fusion line. It is shown that wear resistance of metal of Sormite-1 type deposited on steel 3 by the induction method remains practically unchanged. 6 Ref., 4 Fig.
Keywords: induction surfacing, powderlike hard alloy (Sormite-1), microstructure, wear resistance, natural aging
