摘要

The flow passage components in hydraulic machinery will be eroded rapidly when running in sand water.The wear resistance of materials commonly used in hydraulic machinery needs to be improved to prevent the failure of hydraulic machinery.New wear-resistant materials are urgently needed to improve the service life of hydraulic machinery.Eutectic high entropy alloy (EHEA) is a new kind of alloys with in situ lamellar structure.NiCoCrFeNb0.45 EHEA has combined excellent strength and toughness.In this study,slurry erosion tests of NiCoCrFeNb0.45 EHEA were carried out with different impact angles and impact velocities using a rotary jet erosion test apparatus.The NiCoCrFeNb0.45 EHEA exhibited significant slurry erosion resistance compared with medium carbon steel 1045 and stainless steel 04Crl3Ni5Mo.The erosion rate of EHEA is much slower.Compared with medium carbon steel and stainless steel,the erosion of EHEA is completed via the accumulation and removal of platelets after plowing and work hardening,accompanied by partial micro-cutting.
