Abstract
Diamond was put into iron powder and the surface of the iron powder was heated by a YAG laser beam. The diamond was removed by thermo-chemical reaction between the diamond and the iron powder. The conditions for processing the diamond were examined. The diamond was removed in the iron powder. However, it was not removed in aluminum powder. The iron powder was adhered on the diamond surface during the process. Therefore, the removing method of the adhered iron from the diamond surface was developed. There were the suitable value of the depth and the area of the iron powder for removing process. The suitable irradiating conditions were also examined.
