中文摘要:
      钨电极作为关键热源材料广泛应用于氩弧焊、等离子体焊接、喷涂、切割技术和冶金工业中,而钨电极的抗烧损能力是影响其使用寿命的关键因素。本文介绍了针对不同应用背景,在同等测试环境下,对比不同类型钨电极材料烧损程度。并针对电极工作后形貌和活性物质的变化情况,简要分析探讨了电极烧损机制。钨电极抗烧损性能研究测试方法为钨电极材料的进一步设计选材和工艺优化奠定了基础。
英文摘要:
      Tungsten electrode is widely used as a key heat source material in argon arc welding, plasma welding, spraying, cutting technology and metallurgical industry. The anti-burning ability of the tungsten electrode is the key factor affecting its service life. This paper introduces the comparison of the anti-burning performance of different types of tungsten electrode materials in the Eequivalent test environments for different application backgrounds. Aiming at the changes of morphology and active materials after electrode operation, the mechanism of electrode burning was discussed briefly. The test methodstudy ofon anti-burning performance of tungsten electrode lays a foundation for further design and process optimization of tungsten electrode material.
