The service life of components used in the construction, mining or agricultural industry depends on several factors. Primarily lifespan is influenced by the type of wear to which the parts would be subjected (for example abrasion) and environment in which components perform their function. The choice of material and technology depends on these factors. The part exposed to abrasion can be made entirely from a durable material, which is often quite expensive. Another possible approach is the production of the part from conventional structural steels, such as steel S235JR. Consequently, worn surface can be equipped with a layer of highly wear-resistant material (e.g. by weld deposit) which prolongs the service life of entire component and reduces its repair or replacement costs for producers and customers.This study deals with the evaluation of wear resistance test of selected weld deposits combining FeBNiCr matrix with an increased content of the boron and tungsten carbide particles spread in monolayer weld deposit and all at once with comparing microhardness in selected areas of the welded layer. This weld deposit was made from S235JR structural steel using hard-facing with cored wire in protective atmosphere of argon and carbon dioxide mixture. This contribution also deals with evaluation of mechanisms abrasion which appeared on the surface of the weld deposits in selected areas.
