直读光谱法直接测定中、高铬钢球(锻)中铬含量方法的研究

Study on Direct Determination of Chromium Content in Medium and High Chromium Steel Ball(Forged)Using Direct Reading Spectrometry

文中采用两台不同厂家、型号的直读光谱仪分别对相同的高铬钢球(锻)样品进行测试比对,也与手工化学分析方法的结果进行比对,并利用精密度和统计学理论中t检验分析了检测结果。

In this paper,two direct reading spectrometers of different manufacturers and models are used to test and compare the same high chromium steel ball(forged)samples,and the results are also compared with those from manual chemical analysis.The test results are analyzed by using precision and t-test in statistical theory.
