摘要
Abstract
Piston pump rotor is one of the indispensable parts of hydraulic machinery,whose performance and quality determine the drive efficiency and service life of the piston pump.This paper mainly studies the effect of rare-earth yttrium (Y) on the microstructure and properties of the wear layer in piston pump rotor.The material of the wear layer is composed of lead-tin bronze.By adding different contents of rare earth Y,observe the change of microstructure and properties of lead-tin bronze.Through comparison,the addition of rare-earth Y can improve the tensile strength and elongation of lead-tin bronze,and the organization of lead particle morphology has become much smaller and uniformer than that without rare-earth.However,if the amount of rare-earth is too high,the tensile strength and elongation decrease,and the lead particles in the organization also have the tendency to grow up.Finally,it is concluded that when the amount of rare earth is 0.04％,the comprehensive performance is the best.关键词
