Optimizing Design of B Series Hardfacing Electrode with Wear-resistance and Crack-resistance
The B series hardfacing electrode with the properties of wear-resistance and crack-resistance were designed by orthogonal test. The microstructure of hardfacing was analyzed by the experiments of hardness, metallurgical microstructure, crack-resistance and wear-resistance. The results show that the hardfacing metal has high resistance to crack and crack do not occur even under conditions of non-preheating and non-postheating. The hardfacing metal has high wear-resistance, and its relative wearability is better than that of D667.
