Thermal Spray Coatings

Properties of thermally sprayed coatings by spray process and coating material. Processes: HVOF (high velocity oxy-fuel), APS (atmospheric plasma spray), wire arc spray, detonation gun, and cold spray. Materials: WC-Co and Cr3C2-NiCr carbide cermets, Al2O3/Al2O3-TiO2/Cr2O3/ZrO2-YSZ oxide ceramics, MCrAlY bond coats, NiCr, Stellite 6, 316L stainless, copper, zinc, aluminum, and specialty alloys. Properties: hardness (HV), bond strength (MPa), porosity (%), oxide content (%), surface roughness Ra (um), deposition efficiency (%), thickness range, max service temperature, wear rate, and application guidance.
