Abstract With the self-made erosion test device,the erosion test of HSn70-1A brass and HA177-2A brass was carried out,and the right experiment data were matched into curves.The results showed clearly that the ［Cl-］and sand content influence the erosion.With the ［Cl-］or sand content increasing independently,the material erosion rate increased in a parabolic relationship.HSn70-1A brass was more sensitive to Cl- than HA177-2A brass,but it was more resistant to the erosion of sand in comparison with HA177-2A brass.However,when the sand content was low,the erosion resistance of HA177-2A brass was higher than HSn70-1A brass while in high sand content conditions,the result was just reversed.

Key words: brass erosion ［Cl-］ sand content
