Saint-Gobain Thermal Spray Wire consumables extends the life of components by application of a melted wire coating consumable using an automatic flame spray gun. The flame spray process is available using Saint-Gobain’s Z-Jet flame spray guns to deliver coatings onto many different components.
Wire flame spraying is a combustion process. The oxygen and fuel (propane or acetylene) flame melts the metal wire. Compressed air atomizes the molten metal and propels the particles onto the substrate.
Main applications of wire flame spray include:
Wire arc spray is a form of thermal spraying where two consumable metal wires are fed independently into the spray gun. These wires are then charged and an arc is generated between them. The heat from this arc melts the incoming wire, which is then entrained in an air jet from the gun. This entrained molten feedstock is then deposited onto a substrate with the help of compressed air. This process is commonly used for metallic, heavy coatings.
Main applications for wire arc spray include:
Babbitt #2 is a high tin Babbitt equivalent to ASTM B-23 #2. Babbitt is used as a lining for bearing shells of cast iron, steel and bronze. The Babbitt lining prevents friction and wear that is common when a lubricant is depleted at a bearing surface. Babbitt #2 is typically used for high operating temperatures and high unit load. These materials display very good corrosion resistance, easy bonding and fewer tendencies for segregation. They are preferred for use under steady load conditions in steam and gas turbines, electric motors, blowers and pumps.
Pure copper wire has excellent conductivity and produces dense, well bonded coatings with excellent machinability. Copper is recommended for arc or flame spray and is widely used for electrical conductivity and decorative coatings.
Iron Copper Aluminum cored wire is designed to produce coatings that exhibit moderate surface hardness and are well-bonded to the substrate. This wire can be applied with relatively high deposition efficiencies.
Iron Chrome 13 cored wire contains tungsten carbide in an iron-based amorphous alloy matrix. The carbide component enhances abrasive wear resistance while the amorphous alloy matrix enhances corrosion resistance.
Iron Chrome 29 cored wire is designed to produce very dense, highly erosion resistance surfaces that can be used to resist chemical attack from corrosive environments, even at elevated temperatures. The coating can also be honed or lapped to high surface finishes.
Inconel 622 pre-alloyed wire is appropriate for corrosion resistance in oxidizing and reducing environments, such as for use in boilers. This nickel alloy coating has a high degree of structural integrity, is dense and can tolerate elevated temperatures and oxidizing atmosphere. The addition of chrome enhances its high-temperature corrosion resistance.
Inconel 625 pre-alloyed wire is appropriate for oxidation and hot gas corrosion at elevated temperatures. This wire can also be used for salvage and restoration materials for nickel-based super alloy components.
Ni-Al 95-5 wire is self-bonding to most materials and requires minimal surface preparation. It is also suitable for the build-up and dimensional restoration of nickel-based alloys.
Saint-Gobain’s Ni 20Al is an all purposes bond coat solution designed for either arc of flame spraying. This cored wire has excellent bond strength and is suitable for all base materials including; steel, stainless steels, cast iron, aluminium and super alloys.
Coatings are dense and resistant to oxidation and abrasion.
Nickel-Aluminum-Molybdenum wire produces dense, well-bonded coatings with excellent wear resistance and good corrosion resistance. This wire is widely used for machine repair, dimensional restoration and wear resistance applications.
Saint-Gobain’s Nickel-Chrome-Aluminum wire is designed to produce a self-bonding alloy deposit with excellent high-temperature oxidation and corrosion resistance. The coatings can be used as an undercoat for ceramics and is widely used in the aircraft repair market.
Nickel 43 Chrome wire produces a dense, well-bonded coating with excellent corrosion resistance and good wear resistance. It is highly resistant to sulfur and vanadium atmospheres up to 1825⁰ F. It has proven to be particularly effective as a protective coating for boiler tubes in black liquor recovery boilers and coal-fired utility boilers.
Nickel-Chrome wire is appropriate for corrosion resistance in oxidizing and reducing environments, such as for use in boilers. The coatings produced have a high degree of structural integrity and can tolerate elevated temperatures.
