| Abstract: | The hardness and wear resistance of sprayed FeBSi coating after laser remelting were much improved by addition of 8 wt-% CeO_2.Microstructural observation on the FeBSi+CeO_2 coating revealed that the formation of martensite occurs,as well as the refined grains and the more eutectic and compounds with regular morphology are dis- tributed.While the FeBSi coating free from CeO_2 is a sharp constrast in microstructure. |
| Keywords: | CeO_2 laser remelted coating microstructure FeBSi amorphous powder |
