- Abstract
Application of current diagnostic systems becomes very important in development of fundamental concepts in area of thermal spraying and obtaining of new experimental data, in particular, on plasma-arc wire spraying. Firmware complex based on machine vision camera and digital spectrometer was proposed for experimental study of process of plasma-arc wire spraying of coatings. Procedure for experimental investigations of given process was developed. Results of measurements of velocity and temperature of dispersed phase particles as well as video of the most typical steps of plasma-arc spraying, including detachment of droplets from wire being sprayed and their breaking in plasma flow, were represented. Distribution of particles being sprayed in size was investigated and its effect on possibilities of temperature changes was analyzed. Experimental data obtained verified theoretical representations on types of flow and decomposition of jet of wire molten metal as well as droplet breaking in plasma jet.
