Study on Lining Board with Bimetal Liquid Composite Casting
The effect of chemical constitution, casting technique and heat treatment parameters on microstructure, properties and wearing resistance of the bimetal composite were primarily researched by SEM, EDAX, TEM etc.. The results showed that the higher impact toughness at bimetal combination region than corresponding part of the high carbon steel was obtained. The impact toughness was 23J/cm2 and the hardness of resistant surface was HRC59. The high carbon steel region initiated the impact fracture, however its abrasion resistance was substantially improved over double than Mn13.
