INFLUENCE OF HIGH ENERGY TREATMENT ON WEAR OF EDGES KNIVES OF WOOD-CUTTING TOOL

Abstract

PVD, combined electroplating and PVD methods were applied to increase wear resistance of the hard alloy cutting elements for woodworking. Laminated chipboards milled by a tool with knives were coated with ZrN, Mo-N, and ZrN-Ni-Co layers.  Abrasive wear of tools blades occurred. The wear intensity of the knife blades with deposited coatings was reduced. The value of volume wear of knife blades with coatings was calculated.  If compared with bare tool, wear resistance of ZrN-coated blade increased to 50%, while wear resistance of Mo-N-coated blade increased to 70%.
