Original Abstract

This work is focused on evaluation of quality of hard Al2O3+13%TiO2 and Cr2O3 coatings produced by means of atmospheric plasma spraying technique. The different technological process parameters, namely the plasma torch stand-off distance, gas flow rate, current, particle temperature and velocity were varied during deposition. In-flight particles temperature and velocity were monitored during spraying using Tecnar AccuraSpray G3C (on-line particle monitoring system) unit. Based on the results obtained from AccuraSpray system, 3D optical profilometer, light microscope and scanning electron microscope equipped with energy dispersive microanalyzer, the technological parameters providing optimal microstructure of both studied coatings were identified.
