Preparation of WC-Low Chromium Cast Iron Composite Material by Cast-Infiltration
Use of Low-chromium white cast iron as matrix, WC as reinforcement particles, in conditions of Quartz sand in ordinary water glass dry, non-vacuum, using self-made penetration compound was prepared by WC particles reinforced surface composite material with superior wear resistance, is 2.73 times that of high chromium cast iron composite layer hardness can reach HRC60 or more. Smooth casting surface roughness, dimensional accuracy is more accurate, composite layer and substrate is good.
