Depth profile studies of Zn-coated sheets by LA-ICP-MS, LA-ICP-OES and LIBS

Popis výsledku v původním jazyce

For coatings and layers of thickness between tens of nm and tens of mm, the glow discharge optical emission spectrometry (GD-OES), is currently employed for quantitative depth profiling. Laser ablation (LA) combined with ICP-MS or as an emission source for laser-induced breakdown spectroscopy (LIBS) might be useful tool for the depth profile analysis of coatings with thickness in the range from units to tens of micrometers. However, depth resolution might be deteriorated due to a too large ablation depth per laser shot, a non-uniform radial energy distribution (Gaussian) in the laser beam, and rugosity at the bottom of the crater. Zinc-coated iron sheets (hot dipped and galvanically coated) of thickness between 6 an 30 um were studied by means of LA-ICP-MS system [1]consisting of a homogenized 193 nm ArF* laser ablation system (GeoLas, Microlas, Göttingen, Germany) coupled to an ICP-QMS Agilent 7500 (Agilent Technologies, USA). The sample in the ablation cell can be observed during abl
