【Abstract】 In this paper, microstructural observation and energy spectrum micro analysis and temperature field test have shown that the gray iron cast chromized layer was formed by strong heat transfer and limitary casting chromize kinetics of liquid iron. The forming mechanism is different in the fusion layer, brazing layer and heat agglomerating layer.更多还原
