Abstract
The paper studies the technique for increasing efficiency of high-speed steel tools by forming wear-resistant complexes when using processes of combined cathodic vacuum arc deposition with filtration vapour ion flow. Based on analysis of the causes of premature destruction of standard coatings on high-speed steel tools, provisions were designed to increase the effectiveness of wear-resistant coatings by increasing their operating life till partial or complete destruction. For that purposes, architecture of wear- resistant complex was developed for formation on substrates of high-speed steel. Wear-resistant complex includes thermally stabilizing layer and three-element multi-layered composition nano-dispersion coating, and it can be formed by using the combined process of cathodic vacuum arc deposition with filtration vapour ion flow. The paper presents data on the optimization of the conditions for formation of the wear-resistant complex elements that provide a significant increase in tool life of high-speed steel tool both with continuous and interrupted cutting.
