In order to improve the wear resistance of white cast iron, cermet powder layer only and mixed cermet powder layer added with some metallic elements were inserted by molten 27 mass%Cr white cast iron at 1723 to 1823 K. Various sizes of the cermet powder were adopted for the insertion. The microstructure of the vertical cross-section of the inserted layer was examined to investigate castability of the molten cast iron for these powder layers. The results obtained are as follows. (1) For cermet powder size of more than 3.4mm, the cermet powder layer can be inserted by the molten cast iron. (2) For cermet powder size of less than 3.4mm, the cermet powder layer cannot be inserted, but can be inserted by the addition of Ni powder or Cr powder. This nay be due to the decrease in heat of fusion of the mixed cermet powder and improved castability of the molten cast iron by the addition of the metallic elements to cermet powder. (3) For the mixed cermet powder added with 50 vol.%Ni powder, good microstructure of the inserted layer was obtotned with the compression method used. (4) The suspension of the cermet powder in the mold was also effective for obtaining good microstructure due to good admission of the molten cast iron into the cermet powder.
