CREATING AND STUDY COMBINED WEAR-RESISTANT COATINGS ON CUTTING EDGE KNIVES FOR CUTTING WIRE

The purpose of this article is to conduct comprehensive studies combined wear wearresistant coatings, including their full-scale tests at cutting the wire in the stamp box, assess the effectiveness of wear-resistant coatings, their influence on the stability of the blades, the analysis of the stress-strain state and knives Features of the wear of cutting elements. The method and installation created for comparative testing of various wear-resistant coating on the blades for cutting wire. Full-scale research in cutting wire in automatic mode, press and study the effect of wear-resistant coatings showed increasing stability knives in 2-3,5 times. Established phrase stress distribution in the upper and lower blades of the nature of their wear, fully verifies the results of numerical simulation and correctness of selected design schemes. To investigate the characteristics of the process of wear, a description of the mechanisms of wear, deterioration determining process parameters were held fraktohrafical studies knives.
