3Mechanical behaviors and energy absorption properties of Y/Cr and Ce/Cr coated open-cell nickel-based alloy foams显示文摘In this study,Y-and Ce-modified Cr coatings applied by pack cementation method were prepared on the surface of open-cell nickel-based alloy foam.The morphologies and microstructures of Y-and Ce-modified Cr coatings with various Y and Ce contents were investigated in detail.Then,the effects of Y and Ce addition on the mechanical properties of open-cell nickel-based alloy foams were analyzed and compared.Simultaneously,the energy absorption capacity and energy absorption efficiency of the Y-and Ce-modified Cr coated alloy foams were discussed and compared at the room and high temperatures.The results show that Cr coatings containing minor amounts of rare earth element(Y and Ce) are well adhered to the nickel-based foam struts.Especially,the microstructure of the 2 wt% Ce-modified Cr coating is denser and uniform.In addition,the compressive strength and plateau stress of Y-and Ce-modified Cr coated alloy foams firstly increase and then decrease by increasing the Y and Ce contents at room and high temperatures.The energy absorption capacity of Y/Cr and Ce/Cr coated alloy foams increases linearly with the strains increasing.The Ce/Cr coated alloy foams can absorb more energy than Y/Cr coated alloy foams in the plateau and densification regions at room temperature.Compared to those at room temperature,the Y-and Ce-modified Cr coated alloy foams show higher energy absorption efficiency when deformation within 10%-30% at high temperature.Zhi-Li Hu Qiu Pang Guo-Qiang Ji Gao-Hui Wu 2018Rare Metals2018,37,8:1
