Summary:This paper presents investigation of some operational parameters of coatings for rebuilding, deposited on worn-out cast-iron parts of self-propelled agricultural machines. The coatings have been realized by applying a combined technology comprising deposition of electrochemical coating of non-ferrous metal and subsequently deposition of welding coating. The parameters for deposition of the electrochemical coatings and the parameters for deposition of the welding coatings have been presented. The results of the investigation of the following coatings’ operational parameters are presented: removed material in friction process, friction torque, micro-hardness and roughness. Based on the results obtained, the relative wear resistance of the coatings has been calculated.
