【Abstract】 The abrasion characteristic of the turbine flowed parts was analyzed. It was summarzed that the abrasion of the flowed parts was mostly the erosion, cavitation and their joint action. The primary factor on the elastic was the elastic modulus of materials, and the main factor on the cavitations was the hardness of materials. And the way to increase the abrasion - resistance of flowed parts was found.更多还原
