To ensure the evaporation of the injected coating materials, at the present most very low pressure plasma spraying usually use a high energy plasma gun with the arc currents over 2500A, which could result in the serious corrosion for the plasma torch and require larger power water cooling equipment to cooling plasma torch (Ref 3).
A new thermal plasma torch with separating anode and nozzle was used, and the powder injected into the plasma jets inside the nozzle exit of 25mm, which effectively improved the spraying materials melting in the low pressure environment.

In actual investigation the workpiece material was aluminium (AlMg4,5Mn), in later research the material will be also varied, stainless steel and tungsten are planned to drill.
In the case of aluminium, that strongly adhesive material these phenomena became as important as the wear of the chisel edge.
The adhesive phenomenon of aluminium material can be seen on Fig. 16, where the drilled chip remained in the flute of the twist drill.
