PLASMA SPRAYING PLANT Russian patent published in 2003 - IPC

FIELD: devices and techniques of coatings application, particularly, plants of coatings application by plasma spraying of powder materials to article surfaces. SUBSTANCE: plasma spraying plant uses air as plasma-formation gas and system of combined supply of plasma-formation gas and sprayed powder is made in the form of combination of holes located round cathode in cathode holder. In addition, located between cathode and anode is metal washer-diaphragm electrically connected with anode. Power source in plant consists of main and auxiliary sources. Plasma spraying plant may be used for application of ceramic, metallic and composite powder materials. Plant possesses sufficient power for producing qualitative coatings. Plasma spraying plant is simple in servicing, does not need presence of gas cylinder equipment and may operate from domestic electric mains, for instance, under conditions of stomatologic polyclinics. EFFECT: improved design. 2 dwg, 2 ex
