Deposition of wear resistant layers of strongly allied ferrous filler metal on a base material of iron alloy containing carbon and manganese, said deposition being carried out according to the carbon or manganese content of the base material with or without buffer at low current intensities. The current intensity/filler wire diameter ratio is comprised between 70 and 80 for the wear layer and between 120 and 160 for the buffer. Alloys having a content of 3 to 4 % of Si, 1.5 to 2 % of Mn and C >= 5 % are excellent as filler metals; the alloy containing 5.5 % C, 12.5 % Cr, 2.0 % Mn, 4.0 % Si, 8.0 % Mo, 8.0 % Nb, 2.0 % W, 1.0 % V and 57.0 % Fe is preferred. |
