THE INFLUENCE OF SOME PARAMETERS IN ATMOSPHERIC PLASMA SPRAY OF POWDER 85Ni15Al ON THE PARTICLE VELOCITY

Abstract

The work focuses on the effect of plasma spraying factors such as plasma
current, plasma voltage, and air flow rate on particle velocity because the
effectiveness of the coating is heavily dependent on it. The inclusion of ordinary
air as the plasma-generating gas and the explanation of the mathematical model
justifying the alteration of particle velocity are the innovative aspects of this work.
The newly discovered regression function helps the mathematical model optimize
the procedure to achieve the greatest particle velocity. The parameter validity
study confirmed the good comparative adaptation between the mathematical
model and the experiment results. The introduction paragraph explained why this
study is necessary. The paragraph "Methodology" introduced the equipment,
instrument for analysis, the chemical composition of the material 85Ni15Al. The
paragraph "Experiment" focused on a series of experiments. The multi-criteria
planning design helps to conclude the significance of all parameter and well
adopted to the experiment.
