This paper describes experimental results on the erosion produced by a normal laser radiation and a few examples of spectrochemical analysis of tin-lead alloy samples by using a laser microprobe.
The eroded amount of tin-lead binary alloy, which was calculated from the crater sizes, was dependent upon the heat required to melt the sample.This led to the considerable differences of the eroded amount among various samples with different chemical compositions. Nevertheless it was not observed that these differences influenced directly on the spectrallines intensity.In fact, the analytical curves over the concentration range 10 to 100 percent were obtained and enabled to determine the major constituents of alloy.The application to quantitative analysis of white metals proved that the method was available for convenient microanalysis of alloys.
