Enhancement Of The Wear Resistance Of Tungsten Cobalt Carbide Plates Using Ion Implantation And Al-Si-N Coatings

Producing of cutting tools with high sharpness of the cutting edge (characterized by a small conditional inscribed roundness radius) improves the quality of edge cutting processing of hard-to-cut parts. However, existing carbides do not withstand increased contact loads and quickly destroy. This leads to a deterioration of the quality of the processed surface and to failure of the tool. The paper investigates the influence of different types of processing on the wear of carbide plates. It is found that an increase in the grinding speed leads to a decrease in roughness and an increase in tool life. The efficient ways of the improvement of plate wear resistance are the processing of plates with rhenium and argon ions and the application of thin Al-Si-N coatings.
