Abstract
Wear resistant coatings of highly alloyed filler metal are deposited on base materials of carbon and manganese bearing ferrous alloys and this, depending on the carbon and manganese content of the base material with or without buffer layer, employing low current levels such that the quotient current level/diameter of filler metal wire lies between 70 and 80 and the corresponding quotient for the buffer layer between 120 and 160. Selected as filler metal are alloys containing 3.0-4.5% Si, 1.5-2.0% Mn, and C.gtoreq.5%; preferred is the composition 5.5% C, 12.5% Cr, 2.0% Mn, 4.0% Si, 8.0% Mo, 8.0% Nb, 2.0% W, 1.0% V, 57.0% Fe.
