摘要：传统经典的镀层分析方法分析速度慢，对于不规则镀层样品较难分析，文中在最佳分析条件下，采用激光诱导击穿光谱法对两块不规则未知镀层样品进行分析，镀层分析曲线表明，两块未知镀层样品采用渗锌工艺制备而成，镀层表面的锌、铁元素是主量元素，少量的铬起钝化作用，镀层界面下则是中低合金钢，用一套中低合金钢标准样品建立校准曲线，准确分析了镀层界面下中低合金钢的化学成分及Cr和Mo元素在镀层表面的含量变化情况，从而对未知不规则镀层样品的化学成分有一个深入的了解。

Abstract：Traditional and classical depth profile analysis is very time consuming and difficult to analyze irregular coating sample. In the present work, under optimal parameters, two irregular unknown coating samples were analyzed by laser-induced breakdown spectroscopy. Depth profile analysis curve indicates that zinc diffusion process is adopted for this two unknown samples. Zn and Fe are major elements, and small amount of Cr is used to passivate metal surface. Under the interface, the substrate is medium-low steel alloy, a set of certified reference material for medium-low steel is used to establish calibration curve, and chemical composition of substrates and the concentration variation for Cr and Mo from surface to interface were investigated in detail.

Key words：Laser-induced breakdown spectroscopy;Depth profile analysis;Local microanalysis;Zinc diffusion process
