- Title
PLASMA-POWDER SURFACING OF POWER FITTING RODS.
- Authors
PEREPLYOTCHIKOV, E. F.; RYABTSEV, I. A.
- Abstract
Iron-based filler powder 15Kh19N9M4S5G3D was selected, and technology of mechanized plasma surfacing of sealing and cylindrical surfaces of rods (spindles) of fittings, operating in thermal and nuclear power stations, was developed. Metal deposited with this powder has the required service properties, and its price is lower compared to earlier applied for this purpose nickel alloys. Application of plasma-powder surfacing of rods of power fittings instead of coated-electrode manual arc and automatic flux-cored arc surfacing allowed improving the deposited metal quality, reducing machining tolerances, as well as lowering the surfacing costs and extending the service life of stop valves. 5 Ref., 1 Table, 6 Figures.
