Abstract

In the work presents the results of a study of the influence of the effect of a continuous ion beam of the composition (Ar++Zr+) with an ion energy E ≈ 20 keV and an irradiation dose D ≈ 5·1017 ion/cm2 on the phase composition, chemical state, microhardness, wear resistance during friction against an abrasive and corrosion resistance of tungsten-free hard alloys of the TiC – TiNi system. Analysis of the structure, morphology, and chemical state of the samples before and after ion treatment was carried out using scanning electron and scanning probe microscopy, as well as X-ray photoelectron spectroscopy and X-ray diffraction analysis. The features of the change in the physicochemical state of the tungsten-free hard alloy of the “TiC – TiNi” system subjected to continuous ion beam irradiation are revealed. It has been experimentally established that ion-beam treatment provides an increase in microhardness, wear resistance and corrosion resistance of the hard alloy.

离子束处理下TiC - TiNi系无钨硬质合金的物理化学性质和功能特征

本文研究了离子能量E≈20 keV、辐照剂量D≈5·1017离子/cm2的连续离子束(Ar++Zr+)对TiC - TiNi体系无钨硬质合金的相组成、化学状态、显微硬度、磨料摩擦耐磨性和耐蚀性的影响。利用扫描电子和扫描探针显微镜，以及x射线光电子能谱和x射线衍射分析对离子处理前后样品的结构、形貌和化学状态进行分析。揭示了连续离子束辐照下“TiC - TiNi”系无钨硬质合金的物理化学状态变化特征。实验证明，离子束处理能提高硬质合金的显微硬度、耐磨性和耐腐蚀性。
