Supersonic plasma coating technology

Making use of supersonic plasma coating technology to provide functional coating with surface strengthening for furnace roll in low temperature section and tuyere of blasting furnace , so that the life time is effectively extended.

Rigid non-transferring plasma is taken as thermal resource, atmosphere is heated to be plasma jet flow in high temperature and high speed so that powder sent in jet flow is heated, speeded up and formed to be the melt particle flow, it is shot in high speed to the surface of the part so as to formed coating.

Because temperature of plasma jet flow can be arrived at tens of thousands centigrade, we can make coating in refractory metal, Oxide ceramics and cermet by making use of this plasma technology in order to meet the request for coating layer with high melting point, high purity and high strength in the frontier of aerospace, atomic energy, etc..
