本文研究了火花光源的脉冲频率与灰口铸铁预激发区(预燃区)的金相组织的关系,优选了灰口铸铁中碳的光电直读光谱分析的最佳条件,对灰口铸铁试样的分析获得满意的结果。
In this paper, the relationship between the pulse frequency of the spark source and the microstructure of the gray cast iron pre-ignition zone (pre-combustion zone) was studied. The optimum conditions for direct carbon reading spectroscopy of gray cast iron were optimized. Kind of analysis to obtain satisfactory results.
