Abstract：
The article presents the results of the characterization of the geometric structure of the surface of unalloyed structural steel and alloyed (martensitic) steel subjected to chemical processing. Prior to phosphating, the samples were heat-treated. Both the surfaces and the cross-sections of the samples were investigated. Detailed studies were made using scanning electron microscopy (SEM), XRD, metallographic microscopy, chemical composition analysis and fractal analysis. The characteristics of the surface geometry involved such parameters as circularity, roundness, solidity, Feret\'s diameter, watershed diameter, fractal dimensions and corner frequencies, which were calculated by numerical processing of SEM images.
摘要：
本文介绍了经过化学处理的非合金结构钢和合金（马氏体）钢表面几何结构的表征结果。磷化前,对样品进行热处理。研究了样品的表面和横截面。使用扫描电子显微镜(SEM)进行了详细的研究，XRD,金相显微镜,化学成分分析和分形分析。表面几何形状的特征包括圆度等参数，圆度,坚固性，费雷特的直径，分水岭直径,分形维数和角频率，通过对SEM图像的数值处理进行计算。
