中文摘要：

对空心阴极效应的发热机理及空心阴极等离子烧结铈钨坯工艺进行了初步研究。通过合理地控制电流、电压以及气压等影响因素，获得了持续稳定的空心阴极效应，使其阴极达到2500℃以上的高温。将此高温效应用于烧结高熔点材料一铈钨合金，获得了很好的效果。得到的铈钨烧结坯的密度达到17．8g/cm^3，与垂熔烧结方法获得的密度水平相当。

英文摘要：

The heating mechanism of hollow cathode effect and the technology of hollow cathode plasma sintering cerium-tungsten alloy adobes are researched. A constant and stable hollow cathode effect is achieved by regulating current, voltage, air pressure, with the temperature reaching as high as 2 500℃ or more in the hollow cathode. The high temperature is applied to sinter cerium-tungsten alloy, a high melting point material. The density of ceriumtungsten pieces after sintering reaches 17.8 g/cm^3, which is similar to the density by incipient fusion sintering technique.
