Analysis of 3-μm-thick ZrN, TiN, and ZrTiN ceramic coatings on a high-speed steel substrate by laser ablation inductively coupled plasma atomic emission spectrometry (LA-ICP-AES) is described. A Nd:YAG laser was used in the Q-switched mode and operated at 355 nm and 5 mJ. Ablation patterns were obtained on the target surface by moving the ablation chamber with respect to the laser beam by means of an X-Y translator. Control of the depth of penetration was obtained by successively performing a limited number of cycles. Transient signals were obtained and their peak areas were used for the construction of calibration graphs based on the concentrations determined by energy-dispersive X-ray (EDX) analysis. An erosion rate of 0.1 μm per cycle was observed. Crater shape and depth, temporal behavior, and reproducibility of the signals are described.

Thick Layers

The feasibility of depth profiling of thick layers (>100 μm) consisting of partially stabilized zirconia coating and graded metal—ceramic coating on Inconel steel (ZrO2–Y2O3/NiCrAlY/steel and ZrO2–CeO2/NiCrAlY/steel) was studied on the basis of the use of laser ablation inductively coupled plasma atomic emission spectrometry (LA-ICP-AES). An ICP spectrometer equipped with a multichannel detection was used for the simultaneous measurements of the line intensities. The ablation was performed with a Nd:YAG laser operated in a Q-switched mode at 266 nm. To study the erosion rate, we used either a static or a translation mode for the ablation, and the corresponding temporal behavior of the signals was studied. A higher erosion rate was found for the translation mode when depths higher than several hundred micrometers were probed.
