ABSTRACT:
The invention relates to a process and an apparatus for the plasma deposition of protective coatings and near net shape bodies using induction plasma technology. The apparatus comprises an induction plasma torch in which the particulate material to be deposited is accelerated and injected axially into the discharge. As the particles traverse the plasma they are heated and melted before being deposited by impaction on the substrate placed at the downstream end of the plasma torch facing the plasma jet.
