The Fe-Al intermetallic compounds have a high hardness and superior resistance against a wear, a heat and an oxidation. Therefore it is expected that the compounds will be used as a tool material and a high temperature structural material for a chemical plant, a turbine, a catalyst and so on. The main purpose of this study is to clarify the abrasion characteristic of the Fe-Al intermetallic compounds. In this study, the elastic whetstone of the gelatin base is used as an abrasive stone. Gelatin can control the hardness and a melting point by density, cooling method, cooling time and additives easily. Accordingly a gelatin base stone can produce an elasticity whetstone having various characteristics experimentally. In this study, a new elastic whetstone made of gelatin having new abrasion mechanism is produced experimentally, and the fundamental abrasion characteristic of the Fe-Al intermetallic compound is examined. The main results obtained are as follows. The elastic whetstone produced experimentally can polish the Fe-Al intermetallic compound. Further the surface roughness of the Fe-Al intermetallic compound is improved in a short time so that abrasion speed is fast.
