Research on Preparation and Performance of Wear-resistant Materials for a New Type of Centrifugal Fan Impeller Blades
Considering the wear resistance,process,and economy of centrifugal fan impeller blades,a new type of T8/Q355B explosive composite plate material for centrifugal fan impeller blades was prepared by using the explosive clad weld-ing method that combined T8 with Q355B.The material was heat treated by vacuum quenching at 750,800,850 and 900 ℃ respectively,and it was tested that the hardness and shear strength of the composite plate.The results showed that with the increase of quenching temperature,the hardness and shear strength of the composite plate first increased and then decreased,and the optimal performance was achieved at 850 ℃.The T8/Q355B explosive composite plate with a quenching tempera-ture of 850 ℃ was a material that could be used to manufacture impeller blades.
