在进行高铬钢光谱分析时,观察到不同含碳量对铬钢的工作曲线有影响。同时看到在高碳样品中,样品组织结构也影响了光谱分析的结果。实验证明,在火花光源中,只有当碳是以固溶体状态存在,而且其含量大于1％时,这种影响才比较显著。 根据含碳量对于铬和铁蒸发量影响的数据,我们看到,碳对铬的影响比对铁的影响大。初步认为,在Fe-Cr-C固溶体中,生成Fe-C-Cr键的机率比生成Fe-C-Fe的为大。
In the spectrochemical analysis of high chromium steels, the calibration curve of chromium wasfound to be affected by the difference in carbon content and the microstructure of the samples.This effect became considerable only when carbon was present in the solid solution and its contenthigher than 1％. Experiments show that the presence of carbon affected the volatilization of the different sub-stances from the solid electrodes, and this effect on chromium was greater than on iron. Thus, webelieve in the solid solution the probability of the formation of a Fe-C-Cr bond was greater thanthat of the Fe-C-Fe bond.
