Using inductively coupled plasma mass spectrometry (ICP-MS) for the elemental analysis of Tclass high-speed tool steels is problematic due to their chemical resistance toward acid-based dissolution reagents typically used for ferrous alloys. Development of a suitable method for analysis of high-speed tool steels using available instrumentation, such as ICP-MS, is desirable. In the current study, a hydrogen peroxide-based digest procedure was developed for the dissolution of high-speed tool steels containing 1-18% tungsten, with elemental analysis conducted by ICP-MS. Samples of high-speed tool steels were dissolved in a solution of 6% hydrogen peroxide and 10% aqua regia for determination of tungsten, with subsequent digestion in 50% aqua regia for analysis of remaining alloy elements. The method was successfully applied to a range of high-speed tool steels of different chemical compositions, achieving nearly quantitative recoveries of alloying elements with a high degree of reproducibility. |
