IN DEPTH PHASE ANALYSIS OF BORONIZED LAYER ON ALLOYS BY GLOW DISCHARGE OPTICAL EMISSION SPECTROSCOPY

The distribution of boron and alloy elements in the boronized layer on Armco iron, steel 45, tool steel Cr12Mo, Cr26Mo or stainless steel Cr18Ni9Ti has been determined by a newly developed analytical method GDOS. Based on the contents of boron and alloy elements determined, the in-depth phase composition of borides in layer can be calculated. The results was verified by X-ray diffraction analysis with good agreement.
