| Abstract: | Исследовано влияние воздействия мощных ионных пучков и последующего термического отжига на триботехнические свойства твёрдого сплава. Изменения структурно-фазового состояния и физико-механических характеристик в результате комплексной обработки обеспечивают повышение износостойкости инструментального материала в условиях резания сплавов на основе никеля и титана. |
| Abstract (in another language): | Perspective technological decision of the tool materials wear resistance increasing problem is offered. The method combines surface handening by high power ion beams irradiation and following high temperature anneling. In this paper structure and phase changes in the near-surface layers of the hard alloys WC-Co under high power pulsed ion beams irradiation and its evolution in the course of high temperature anneling have been investigated. As a result of thermal effect in near-surface of the area the layer with high strength is formed.This layer defines tribological properties of a material. It excludes fragile destruction of a tool material and promotes increase of wear resistance. The kinetic of wear of modified tool alloys during cutting is established. New method of modification provides the improvement of wear resistance of toll at cutting steel, nickel and titanium alloys. Distinctive features of the thermal anneling: availability of many phases outside of dependence on regimes of the preliminary ion beam irradiation; the low density of defects of a WC-phase in comparison with the irradiated samples only (extended mosaic structure, low dislocation density and defects of packing, the reduced microdistortions of a crystal lattice); high degree of perfection of a crystal structure of a Co-phase. |
