利用扫描电镜、Ｘ射线衍射仪、Ｘ光能谱仪以及浆罐式冲蚀磨损试验机研究了２Ｃｒ１３不锈钢表面激光熔覆Ｎｉ／５０％Ｃｒ_３ Ｃ_２复合涂层的组织和冲蚀磨损性能Ｎｉ／５０％Ｃｒ_３Ｃ_２激光熔覆层由细密的奥氏体枝晶和枝晶间的γ－Ｍ_７，Ｃ_３共晶体所组成，其显微硬度范围为３５０－４５０ＨＶ。在含有Ｈ_２ＳＯ_４和 ＮａＣｌ的砂浆水溶液中且冲击角为 ４５°的情况下，冲蚀磨损率随冲击速度和酸性介质浓度的提高而增加，Ｎｉ／５０％Ｃｒ_３Ｃ_２复合涂层冲蚀磨损表面形貌的典型特征为铲削坑和挤出唇。
The microstructure of stainless steel 2Cr13 laser cladding Ni / 50% Cr_3 C_2 composite coating properties and erosion Ni / 50 scanning electron microscope, X-ray diffraction, X-ray spectrometer and the plasma erosion and wear tester tank The% Cr_3C_2 laser cladding layer consists of γ-M_7, C_3 eutectic between fine dendrites and dendrites, and has a microhardness range of 350-450HV. In the case of mortars containing an aqueous solution of NaCl and H_2SO_4 and impact angle of 45 °, the erosion wear rate and improve the impact velocity with the acidic medium concentration increased, Ni / 50% Cr_3C_2 composite coating erosion surface morphology Typical features are shovels and extrusion lips.
