Study on Metallography and Properties of WC Cast-Infiltration on Carbon Steel Surface by Expendable Pattern Casting
With expendable pattern casting, WC infiltrated layer on carbon steel surface can be gained. Metallography of infiltrated layer was researched, hardness of infiltrated layer was tested and wear resistance was also tested on ML－100 attrition testing machine. Experimental results shoes that: microstructure of infiltrated layer is made up of pearlite, ferrite and WC particle, Brinell hardness of infiltrated layer is 1.7 times that of the matrix and wear resistance is 2.97 times that of the matrix.
