The regeneration of the tools to cellulose cutting using electric arc surfacing method

Abstract

The regeneration of the tools to cellulose cutting using electric arc surfacing method. The paper presents the laboratory results of the regeneration of the tools to cellulose cutting, using electric arc surfacing method. Three types of regenerating material was used in the rod electrodes form. Additionally, each material was applied with additional non-magnetic powder in the coating. Finally, the layer with the highest microhardness was covered with a ZrN coating in the Arc PVD process. The relative wear coefficient, the friction moment, the friction coefficient, the width of friction track and the microhardness were measured. The SEM observations and EDS investigations were applied for the studies of the microstructure of investigated materials. The best results were obtained for the regeneration using regenerating material, marked as “T-590 + powder”, with ZrN coating.
