The thermal spraying material and coating function and application
A: thermal spraying materials
Has been realized in the practical application in industrial production of coating materials such as metals, alloys and ceramics, mainly used in powder, wire and bar state, including spraying powder for spraying materials more than 70% of the total amount. Used as a coating material are:
1, thermal spraying powder
Pure metal powder: W, Mo, Al, Cu, Ni, Ti, Ta, Nb, etc
Alloy powder: Al - Ni, Ni - Cr, Ti, Ni, Co - Cr - Ni - Cr - Al, W, MCrAlY (M = Co, Ni, Fe), Co, Ni, Fe base metal, etc
Oxide ceramic powder: Al2O3, ZrO2, Cr2O3, TiO2, etc
Carbide powder: WC, TiC, Cr3C2, etc
Metal ceramic powder: WC - Co, Cr3C2, NiCr, etc
Plastic powder: nylon, polyethylene, PPS etc
2, thermal spray wires
Al, Cu and zinc, Sn, Al - zinc alloy, babbitt alloy, stainless steel,
Ni - Al wire, etc.
3, thermal spray bar
Al2O3, ZrO2, Cr2O3, etc
B: coating functions and applications
Resistance to high temperature oxidation and hot corrosion coating
For some exposed to high temperature corrosion in the gas components, corrosion under high temperature, gas and air flow scouring role, seriously affected the life and safe operation of the equipment. Resistance to high temperature oxidation and hot corrosion materials besides must resist high temperature oxidation and corrosion, must also have similar to the substrate material thermal expansion coefficient, party by local overheating temperature cycles and led to the decrease of the coating thermal fatigue resistance. Used as high temperature oxidation resistance and high temperature corrosion coating material has: NiCr, leicester, MCrAl, MCrAlY (M = Co, Ni, Fe) and Hastiloy and Stellite alloy, etc. This kind of coating of four typical applications such as power plant boiler tubes (water wall tube, reheater tube, superheater tube and economizer tubes) and high temperature oxidation corrosion of water wall and so on has been the electric power, papermaking, chemical industry and other industrial boiler users need to solve the problem, after years of research, the practice has proved that the electric arc spraying Ni - Cr, Fe - Cr - Al, Ni - Cr - Al, 45 ct coating can get good protection, the service life of up to nine years. MCrAlY coating used for aviation engine turbine blades and turbine engine combustion chamber, such as flame tube with thermal barrier coating bonding layer.
