Metal and Metal Alloy Thermal Spray Coatings

Metal and Metal Alloy Thermal Spray Coatings

• Metal alloys can be used as bond coatings for other thermal spray coatings
• Nickel and Ni alloys such as NiAl are commonly used for dimensional buildup of parts for ease of machining
• Stainless steel, NiCr, etc. can be used to restore dimensions or to put an improved surface for wear and corrosion.
• Stellite, Triballoy, and other tribological materials can be used for improved performance over an easily fabricated base material.
• Molybdenum (Mo) and other refractory metals can be used for high temperature wear resistance, for sliding wear, and applications requiring lubricity
• Cobalt (Co), Tantalum (Ta), Chromium (Cr), Tungsten (W) and similar types of materials offer specialized properties.
• Copper (Cu) and Aluminum (Al) based materials are used for corrosion resistance, electrical conductivity, thermal conductivity, and other applications
• MCrAlY’s, such as CoCAlY, NiCrAlY, CoNiCrAlY and NiCoCrAlY, are used for hot oxidation protection and corrosion protection in gas turbine applications and in high temperature wear and corrosion up to 1000°C.  They are also excellent bond coat materials.

Common coatings:

• MCrAlY’s (NiCrAlY, CoCrAlY, NiCoCrAlY, CoNiCrAlY)
• Nickel Aluminum alloys (NiAl)
• Nichrome (NiCr)
• Molybdenum (Mo)
• Titanium (Ti)
• Stellite
• Triballoy
