Abstract: This research indicates the possibility to replace commercial materials and surfacing techniques by submerged arc welding under the flux and powder of industrial waste materials to obtain the chute with high abrasive wear resistance but for a lower price. Industrial waste of hard metal inserts, emery wheels, chips of case hardened stainless steels were grinded, granulated and blended. Prepared powder mixture served as alloying source increasing precipitation of hard particles during solidification of the weld. Abrasive wear resistance of coating six times exceeds wear resistance of industrial materials, while hardness exhibited very similar values. The results presented in this paper are based on micro-structural analysis of the surfaced and commercial coatings and are supported by analyses of the hardness and abrasive wear resistance. The complementary value of this research is a possibility to recycle industrial waste, which accumulates in huge quantities in the metals working industry.
