EFFECT OF CeO_2 ON MICROSTRUCTURE AND WEAR RESISTANCE OF LASER REMELTING FeBSi COATING
|
Abstract:
The hardness and wear resistance of sprayed FeBSi coating after laser remelt-ing were much improved by addition of 8% CeO_2. Microstructural observation on theFeBSi+CeO_2 coating revealed that the formation of martensite occurs, as well as the refinedgrains and the more eutectics and compounds with regular morphology are distributed. Whilethe FeBSi coating free from CeO_2 is a sharp constrast in microstructure.
