【Abstract】 This paper investigates the graphitizing effect of Al-alloyed coating on the surface of the grooves on the gray iron weld and bond metal. Based on it, a powerful graphitized coating flux is developed, capable of reducing weld hardness and eliminating white iron of the partial melting region so as to enhance its crack resistance.更多还原
