Arc plasma has many advantages, such as high temperature、 high energydensity and so on. It has been applied in the field of cutting、 welding、 metallurgyand material prepared etc, but there is a long-term problem in the field of the arcplasma technology, which is how to reduce cathode erosion to increase the life-timeof arc plasma generator, so many scholars in the world have been studying theproblem on the cathode erosion.

电弧等离子体具有温度高、能量密度大和对环境污染小等特点，它已被广泛应用于切割、焊接、冶金、材料制备等领域，但是在电弧等离子体技术中，怎样减少阴极烧损提高等离子体发生器的寿命是电弧等离子体技术中一个长期问题，因而国内外的许多学者仍在对阴极烧损这个问题进行研究；本文围绕&通过提高阴极表面温度，增强阴极表面的电子发射能力，来增大阴极弧根直径，进而降低电弧通过阴极弧根传入阴极表面的有效比热流，以达到减小阴极烧损的目的。&
