堆焊焊条组织和性能的研究

Study on Structure and Properties of Hardfacing Electrode

针对冶金工业设备零部件的特点，研制出一种具有良好的高温硬度、耐磨性、耐热性和使用性能的堆焊焊条，对其堆焊层的组织和性能进行较系统的试验研究。

In view of the characteristics of the machine parts for the metallurgical industry,a hardfacing electrode has been developed that has better high temperature hardness,wear resistance,heat resistance and service performances and a systematic experimental research been done on the structure and properties of its hardfacing layer.
