The thermal spraying material and coating function and application
A.the thermal spraying material
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 function and application
1, antiwear coating
Wear industry equipment damage is one of the main reasons that may lead to abrasion working conditions including micro vibration, sliding, shock, abrasion, erosion, etc. Wear resistance coating should be hard, but also the performance of the heat resistance and resistance to chemical corrosion. Fe, Ni, Co in the metal and WC - Co and Cr3C2 - NiCr metal ceramic, Al2O3 and Cr2O3 ceramic material has these properties. The coating technology improve the surface wear resistance has a very wide range of applications, such as piston ring, the gear synchronous ring spraying Mo coating, textile machinery parts and components such as roller, spinning hook on the spraying and fiber resistance of Al2O3, Al2O3 and TiO2 ceramic coating, pump and valve sealing surface coating Cr2O3, WC - Co wear-resistant coating, high power and large truck crankshaft mill, exhaust fan shaft using Fe base alloy material repair wear and abrasion resistant reinforcement, etc.
2, anticorrosion coating
Long exposure to outdoor atmosphere (Marine, industrial and urban and rural atmosphere) and different medium (water, river water solvent and oil, etc.) in the environment of large steel structures, such as power transmission tower, steel structure bridge, offshore drilling platform, derrick in coal mine, and all kinds of chemical containers such as storage tanks, etc., by different degree of oxidation and erosion environment. With Al, zinc, and Al - zinc alloy and stainless steel protective coating, can obtain long-term protective effect for 20 years. Some components by gas corrosion and chemical corrosion, can according to the specific conditions (such as the medium, concentration, temperature, pressure, etc.) select the appropriate coating materials such as metals, alloys, ceramics and plastic for protection.
3, high temperature oxidation and hot corrosion resistance coating
For some exposure to high temperature corrosion in the gas components, by high temperature, gas corrosion, and the function of air flow scouring, seriously affected the life and safe operation of the equipment. In addition to high temperature oxidation and hot corrosion resistance of materials must be resistant to high temperature oxidation and corrosion, must also have similar to the substrate material coefficient of thermal expansion, the party won't be caused by local overheat temperature cycle and the coating thermal fatigue performance degradation. Used as high temperature oxidation and hot corrosion resistance of 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 and economizer, superheater tube) and water wall of high temperature oxidation corrosion has been electric power, papermaking, chemical industry and other industrial boiler users need to solve the problem, after years of research and practice has proved that the electric arc spraying Ni - Cr, Fe - Cr - Al and Ni - Cr - Al, 45 ct coating can achieve a good protective effect, the service life of up to nine years. MCrAlY coating used in aviation turbine engine blade coating as well as turbine engine combustion chamber, such as flame tube with a thermal barrier coating bonding layer.
