H.V.O.F Coating
This is a new spraying method to use the added heat and accelerate energy of jet flow(Speed: 2100 m/sec or more) of ultra speed extracted in high pressure condition (combustion pressure: 13 Bar) from the rocket combustion room to make the softening and accelerating for thermal spray materials by the maximum collision motion energy in a way of forming the extremely high close density film. For the thermal spray materials, there are metals with low fusion point, non-metal, ultra light alloy, metal carbides(WC), boron hydrides, and the flight speed of the thermal spray materials is extremely fast (Speed: 900m/sec or faster) that the staying time in the air is short, resulting in almost no change of property (oxidation and deformation), and it enables to obtain the ultra light film (W.C.: DPH 300 1400) of strong tissue with the finite density.coating image
