Study and Application on Surface Composites by WC Particles/ High Chrome Cast-iron
To increase the wear resistance of back board, WC particles reinforcement-phase/high chromium cast iron were formed on the surface of gray cast iron, by using cast-in-place hardfacing technology. The wearability and microstructure of composite material were analysed.Under the complex running conditions of abrasive wear.erosion wear and corrosive wear,the composite material back board has good wear resistance,the manufacturing process is very simple, and used in production.
