The effect of coating with deposited metal, containing wolfram carbide, on surface layer properties and life-time of ploughshare was evaluated in this paper. At the initial stage of testing on the wearing machine, the coatings obtained by surface welding with cored rod. coated rod or welding powder wire were evaluated in terms of their resistance to wearing. The obtained results were verified in field studies of ploughshare, during natural exploitation in different soil conditions. It was found that the increase in life-time of coated ploughshare depends, above all. on soil properties.
