A high deposition rate method of coating cylinder bores was developed. This process, the plasma rotating electrode coating process (PROTEC) utilized transferred arc melting of a rapidly rotating rod. This produced droplets which were accelerated toward the inside walls of a cylindrical substrate placed in the droplet flight path. The process was demonstrated through the coating of aluminum cylinder bores with 1045 steel. Plasma gas was shown to affect particle size and therefore coating microstructure. Rotational velocity of the consumable anode affected particle size and velocity, causing variations in coating microstructure and coating/substrate adhesion.
