摘要
Abstract
To enhance the service life of pumps operating under combined erosion-corrosion conditions,the fabrication of impellers using tungsten carbide(WC),known for its exceptional wear and corrosion resistance,is crucial.This study em-ploys Powder Extrusion Printing(PEP),an additive manufacturing technology,to fabricate WC-10Ni components.The work systematically investigates the influence of process parameters on the forming accuracy of green bodies and the effect of sin-tering parameters on the microstructure of the material.The results indicate that higher green body forming accuracy effec-tively minimizes internal defects.After distributed debinding and low-pressure sintering at 1 520 ℃,the resulting WC-10Ni alloy exhibits a fine and uniform microstructure,high density,and mechanical properties significantly superior to those of samples prepared by conventional powder metallurgy methods.Based on the optimized process,a high-density WC-10Ni im-peller measuring Ø233 mm×93 mm was successfully fabricated.This study provides valuable guidance for the manufactur-ing of high-performance tungsten carbide components with complex geometries.关键词
