Preparation of Ni-containing Coating by Infiltration on Pure Tungsten Surface AITranslate
Abstract AITranslate
In order to realize W-Cu metallurgical bonding,Ni-containing coating was prepared on pure tungsten surface by infiltration in different melts. The microstructures and composition distribution of coating/ tungsten interface were studied by SEM and EDS. The results show that metallurgical bonding between coating and tungsten forms, including Ni-Fe coating,Ni-Cu coating and Ni coating prepared at 1 500 ℃ in Ni-Fe melt, Ni melt and Ni-Cu melt, respectively. There is tungsten-based high density alloy microstructure composed of smooth W particle phase and a small amount of binder phase on Ni-Fe coating and tungsten interface. A 1-2 μm thick compound layer composed of NiW and NiW2 forms along Ni coating and tungsten interface. Based on experimental results and W-Ni binary phase diagram,Formation mechanism of the microstructure on coating/tungsten interface is analyzed.
