Abstract
The invention provides a nozzle. The surface(s) of the inner wall and/or the outer wall of the nozzle is/are coated with a layer(s) of material. The service life of the nozzle is effectively prolonged. The splash adsorption force at high temperature of the nozzle with the coating material is greatly reduced, so that splash can be cleared easily; the nozzle with the coating can prevent parent metal from being glued away when splash is cleared; the nozzle with the coating guarantees high hardness of the parent metal at high temperature and prevents the parent metal from deforming; the nozzle with the insulation coating can reduce the risks of fire striking and short circuit occurring when the nozzle touches work pieces; the nozzle with the coating can reduce the splash clearing efficiency; with the coating, heat dissipation is better than red copper radiation heat dissipation, and the service life is prolonged; with the coating, the external force impact resistance of the nozzle is greater than that of ceramics; the coating does not flake; post-impact deformation is small; the nozzle with the coating is great in thermal shock resistance; even the nozzle is cooled suddenly from a high temperature of 800 DEG C to 0 DEG C, material does not fall off.

Further, the inwall of described nozzle and/or outer wall surface are coated with layer of material and specifically include following one of which:
Whole inner-wall sprayings at described nozzle have layer of material；
Whole exterior wall at described nozzle are coated with layer of material；
Being coated with layer of material at the internal partial wall near near electric arc and/or outer wall, the remainder of described nozzle does not sprays.
Further, described material is insulant or semi insulating material or conductive material.
Further, described material is hot superconducting nano ceramic coating or for nonmetallic ceramics coating or for the one in metal-cermic coating or its combination in any mixing material.
Further, described material is high rigidity hot superconducting nano ceramic coating, and heat loss through radiation is better than red copper, has self-cleaning function.
Further, described material is soft hot superconducting nano ceramic coating, has soft, and heat loss through radiation is better than red copper, smooth surface, has the strongest self-cleaning function.
Using technical scheme, have the advantages that, greatly reduce splashing absorption affinity under cated nozzle high temperature, as easy as rolling off a log cleaning is splashed；Under cated nozzle high temperature, cleaning is splashed " not glue " and is walked mother metal；Under cated nozzle guard mother metal high temperature, high rigidity and mother metal are indeformable；The nozzle having insulating coating reduces nozzle and encounters workpiece and the risk of short circuit of striking sparks；Cated nozzle reduces cleaning spattering frequency；After applying coating than red copper heat loss through radiation more fortunately, increase the service life；The well pottery of cated nozzle resistance to external impacts performance, coating will not flaking；Deform little after impact；Cated nozzle resistance to sudden heating is fine: being cooled to 0 degree rapidly from 800 celsius temperatures, material does not falls off yet.
