| Outline of Final Research Achievements |
The purpose of this research was to development and evaluation of a high-temperature wear resistance casting composite material which carried out partial reinforcement by cermet particles (new material and used). Reinforcement layer was formed at arbitrary positions by using the preform which made from cermet particles mixed with Ni and Cr powder and cured by sodium silicate CO2 process. The four-point bending strength of the composite material was from 300 to 570MPa. We showed clearly that the bending strength was dependent on the interface strength between cermet particles and a base material, and proposed the method of the improvement in strength based on this. Moreover, high-temperature wear resistance of composite material was improved up to octuple of maximum compared with the base material of heat-resistant cast steel cast.
