Investigation of Properties of Multilayer Nitride CrN/NbN Coatings According to Acoustic Emission Parameters. Pt. 1. Multilayer CrN/NbN Coatings with a Double-Layer Thickness of 230 nm

Popis výsledku v původním jazyce

The evaluation method for acoustic emission, which detects the elastic waves emitted during cracking and delamination of the vacuum-arc multilayer nitride CrN/NbN coatings, is used for investigation of the coating properties. The investigation is conducted using scratch testing and microscopic visual observation of scratches. To compare the properties of multilayer CrN/NbN coatings obtained at different technological parameters of deposition as well as to determine and evaluate the processes occurring during the coating deformation, methods for statistical data analysis for acoustic emission are applied. The maximum pulse amplitude, the average value, the median value, the mode value, the number of pulses, and the amplitude sum of all acoustic emission pulses for each coating are calculated. The multilayer CrN/NbN coatings consist of 68 layers with bilayer thickness of 230 nm. To increase the calculation reliability, the studied parameters are calculated on four scratches for each multilayer coating. The influence of deposition technological parameters on the structure deformation processes of multilayer CrN/NbN coatings occurred during scratch testing is determined.
