“…In overlay welding, it typically melts and precipitates as hard hexagonal close-packed (hcp) Cr 7 C 3 and face centered cubic (fcc) Cr 23 C 6 or mixed M 7 C 3 and M 23 C 6 secondary carbides [14][15][16][17][18][19][20][21]. Chromium carbide reinforced overlay welded coatings have been developed, for instance, for cutting knives [22], nuclear reactor components [16], well drilling and oil extraction equipment [19], dies and molds [15], hot rolling mill rolls [20], and boiler tubes [23]. The developed coatings have been found to improve significantly high temperature (HT) sliding wear resistance of cast steels [20], HT oxidation and erosion-corrosion resistance of martensitic stainless steel [15,19], and sliding wear resistance of austenitic stainless steel [18].…”
