Abstract
Effectiveness of application of electric arc metallizing for restoration of worn-out parts of the machines is outlined. Adding of different components, ferrophosphorus in particular, into the charge of flux-cored wires, can decrease significantly the coefficient of friction and wear of coatings in metallizing and increase the service life of the as-restored parts.
Keywords: electric arc metallizing, flux-cored wire, thermal coating, wear, wear resistance, coefficient of friction, phase transformations, lubricant, graphite, ferrophosphorus, calcium fluoride
