A plasma spray coating for titanium particles using software simulation

In the present study, a plasma spray coating for titanium particles was studied using software simulations. The governing equations to solve the velocity and temperature distributions of plasma flow and titanium particles considered the effects of electric/magnetic inductions. Seven controlling factors were included in order to investigate their effects on the velocity and temperature of titanium particles colliding with the specimen substrate and the colliding scope of the effective particle depositions. The velocity and temperature distributions of the plasma flow predicted in the present study were expressed in a power form. The results predicted by the present governing equations were thus trustworthy. In general, either a small particle diameter in collaboration with a low electric potential or a large particle diameter in collaboration with a high electric potential is advantageous for a high melting and boiling points.
