Abstract

The purpose of this work is experimental research of properties of superficial layer of material, utillized for making of knives of bowl cutter, after his consolidating impulsive-plasma treatment. Bowl cutters are one of basic types of techno-logical equipment, determining amount and quality of the made sausage wares in industrial terms. Expedient is a ground of choice of such method of increase of longevity of knives, which will possess high efficiency and will be suitable to the wide industrial use. High technical and economical indexes are possessed by technology of the impulsive-plasma consolidating. However, not looking on the positive results of industrial tests of the consolidated cutting instrument, in literature quantita-tive information absent about properties of superficial layer of materials, utilized for making of knives of bowl cutter. It lim-its possibilities of search of new more effective ways of increase of wearproofness of this type of cutting instrument. Most by the widely applied material for making of knives of bowl cutter there is steel of 65Г in domestic terms. With the purpose of determination of influencing of the impulsive-plasma consolidating on the structure of material of the processed instrument and choice of the most optimum modes of treatment microstructure researches were conducted. They consisted of such stages: making of pre-production models which on the geometrical and physics and mechanical properties answered the cuttings edges of the probed knives of bowl cutter; impulsive-plasma consolidating of standards; laboratory re-searches. The impulsive-plasma consolidating was carried out on setting «IMPULSE» of laboratory of Institute of the electric welding the name of E.O. Paton of NAS of Ukraine. Is it set that maximal values of micro-solid (HV50=11000 MPa) and thickness of the consolidated layer (10 мкм) arrived at during realization of 3 impulses of plasma treatment pithily at the ca-pacity of condenser battery of bit contour of C=800 мicro-F, tension on the covers of condenser battery of U=3,2 kV, to in-ductance of bit contour of L=30 micro-F and frequency of initiating impulses 2,5 Nz. The got results allow to consider expe-dient the use of the impulsive-plasma consolidating for the increase of longevity of knives of bowl cutter.
