Paper Abstract

This paper contains experimental results obtained by applying both one-side and two-side diffusivity measurement procedure for Russian-made cutting tools. Experimental set included CO2 laser with energy up to 12 J in 4 ms pulse and diffusivity measurement device TAU- 1. In two-side test the correlation coefficient between wear resistance and obtained value of diffusivity was estimated to be K equals -0.61. In one-side test the ratio of signals at 6 and 9 ms after flash was accepted as wear resistance criterion. The corresponding correlation coefficient was K equals 0.59. Some results obtained with Swedish-made tools of unknown composition are also discussed.
