摘要：

NiCoCrAlY/Al2O3 and NiCoCrAlY/B4C composite powders were prepared with hydrogen reduction and solid state alloying process. NiCoCrAlY/Al2O3-B4C composite coatings with different contents of B4C were prepared by atmospheric plasma spray technology. The microstructures, mechanical properties, and tribological properties of the composite coatings with different B4C contents were systematically investigated. The results show that the microhardness of the composite coatings increases, while the tensile strength of the composite coatings decreases, with the increase of B4C contents. The wear volume of the composite coatings decreases from room temperature to 800 A degrees C with the increase of B4C contents. Abrasion wear is the main wear mechanism of the NiCoCrAlY/Al2O3-B4C composite coating from room temperature to 800 A degrees C.
