本文介绍利用溶液法和粉末法进行合金钢光谱分析的方法,以克服制备标准样品的困难和消除样品组织结构和物理状态的影响。将钢样溶解于酸制成的溶液,滴在平头碳电极上用火花激发,或将钢样制成氧化物粉末,填于碳孔中,用交流电弧激发。初步结果指出,这些方法可以满足一般分析要求。 This article describes the use of solution and powder method for the analysis of alloy steel methods to overcome the difficulty of preparing standard samples and eliminate the sample structure and physical state impact. The steel sample is dissolved in acid solution, dripped in a flat carbon electrode with a spark excitation, or the steel sample made of oxide powder, filled in carbon holes, with an AC arc excitation. Preliminary results indicate that these methods meet the general analysis requirements.
