In several plants,a few NH4C1 are added to Al2O3 (as a packing material) during the activated sintering process of sintered carbides in order to lower the sintering temperature from 1450℃ to about 1250℃, whereas corundum tubes of sintering furnace deteriorate abnormally, A thermodynamical analysis has been given in this paper to exlpain the deterioration mechanism. It is shown that the cause of the abnormal deterioration of corudum tubes is that the CaO impurity, as a constituent included in tube material, reacts chemically with HCl gas decomposed from NH4Cl at high temperature. The conclusion has been verified by experiments and it will not be affected by the existent forms of different impurities. 本文从热力学计算及实验结果,探讨了活化烧结硬质合金时烧结炉刚玉炉管非正常损坏的机理。对制订特殊烧结工艺,有一定参考价值。 Among the corrosion resistant hard metals an investigation for the corrosion resistance of the WC base metal is of particular importance, since this metal is more universal in use.

The present paper studies the influence of quantity of palladium added in molybdenum, sintering temperature and sintering time on densities of molybdenum The experiments show that optimum quantity of palladium is around 0.5wt.％.The optimum sintering temperature of molybdenum with about 0.5wt.％ pd is at 1150℃.The characteristic exponent(n) for indicating dominant densifieation mechanism and apperent activation energy(Q) were calculated by using experimenltal data.The n and Q obtained is 3.1-3.4 and 61-62.5 kcal mol~(-1) respectively. It is concluded that the activated sintering mechanism of molybdenum by palladium is mainly derived from boundary diffusion. Some cosiderations of the distribution state of palladium on the surface of molybdenum particles are also given in this paper 本文研究了钯的加入量、烧结温度和烧结时间对钼的密度的影响。实验结果表明,钯的最适宜的加入量为0.5wt％左右。在这个最佳量下钼的最适宜的烧结温度为1150℃。利用实验数据计算了钯活化钼烧结的控制收缩机理的特性指数n和表观活化能Q。得习n为3.1—3.4和Q为61—62.5kcal/mol。从而得出钯活化钼的烧结机理以晶界扩散为主。本文对钯在钼粉粒子表面上的分布状态,提出了看法。   << 更多相关文摘      相关查询 activated sintering agents field activated sintering plasma activated sintering activated sintering of powder sintering activated liquid phase activated sintering sintering bodies compact sintering mechanically activated sintering shaping sintering forming
