Depth profile studies of ZrTiN coatings by laser ablation inductively coupled plasma mass spectrometry
Original language description
Abstract Feasibility of depth profiling was studied using a 193 nm ArF* excimer laser ablation system (GeoLas, MicroLas, Goettingen, Germany) with the lens-array-based beam homogenizer in combination with ICP-QMS Agilent 7500. Two ablation cells (20 cm3and 1.5 cm3) were compared at the laser repetition rate of 1Hz, laser beam energy of 135 mJ and the carrier gas flow rate 1.5 L/min He + 0.78 L/min Ar. Dimensions of ablation cell are important parameters for signal tailing, however; very small cell volumes (e.g. 1.5 cm3) may cause memory effects, which can be probably explained by dominant inertial losses of aerosol on cell walls with its delayed mobilization. The 20-cm3-ablation cell seems to be appropriate for depth profiling by continuous single-hole drilling. The study of influence of the pit diameter magnitude on courses of waning and emerging signals under small crater depth/diameter aspect ratio, which ranges between 0.75 and 0.0375 for the 3-ěm thick coatings and pit diameters
