The purpose of this work is to analyze cermet tools by using EPMA, which is a simpler and a more economical method, and to estimate their cutting performance.
First, the examination was made to confirm the fact that analyzed elements were not influenced by other elements. The calibration curves for Ti, Mo, and Ni were drawn from the standard specimens. These diagrams show that the X-ray intensity is proportional to the percentage of each element contained in the cermet tools. It appeared that each element in the cermet tools didn't form perfect solid solution but exists for the most part as a single element. The specimens whose contents are not to the public have been analyzed according to these curves. Reliable estimation for the cutting performance have been given by data of the analysis.
