研究了不同方法的热处理和化学热处理对碳化钨硬质合金(BK15)、碳化铬硬质合金(KXH25)和钢结碳化钛硬质合金(КТЖХ-50)(50%TiC+50%Cr15钢)抗弯强度和水磨粒磨损的影响。试样的热处理和化学热处理,在耐热合金制的容器里于氢或氮的气氛中进行(表1)。水磨粒磨损试验按СХЕМАШТАУФФЕРА进行,将0.1~0.3mm含5%水的石英砂悬浮液作为磨料介质,转子转速为950r/min(v=7.5 m/s),试验时间为48小时,使用АДВ200M型重量分析仪,根据被测试样重量的减少来评定磨损程度。其结果见图1。由图1可见,以方式1和2进行处理时,
The influence of different methods of heat treatment and chemical heat treatment on the mechanical properties of tungsten carbide (BK15), chromium carbide carbide (KXH25) and titanium carbide КТЖХ-50 (50% TiC + 50% Cr15 steel) Bending strength and wear of abrasive particles. The heat treatment and chemical heat treatment of the sample were carried out in an atmosphere of hydrogen or nitrogen in a heat-resistant alloy container (Table 1). Water abrasive wear test by СХЕМАШТАУФФЕРА, the 0.1 ~ 0.3mm 5% water containing quartz sand suspension as abrasive medium, the rotor speed of 950r / min (v = 7.5 m / s), the test time was 48 hours, using АДВ200M Gravimetric analyzer, which evaluates the degree of wear based on the weight loss of the test specimen. The results shown in Figure 1. As can be seen from Figure 1, when processed in modes 1 and 2,
