What materials can be thermally sprayed?

Any material that passes through a melting phase when heated. This includes metals, metal alloys, carbides, ceramics & some plastics materials that go from solid to a gaseous phase when heated, e.g. wood cannot be sprayed.

Plasma

The plasma process has evolved over the years into a highly flexible coatings system capable of applying a wide range of materials. These include most metals/alloys, ceramics, cermets and composites. Main Applications Main Industries served: Aerospace Energy / power generation Automotive Petrochemical Mining Textile Print Plasma Process Description An inert gas (typically Argon), when excited […]

High Velocity Oxy-Fuel

HVOF spraying has been developed principally to produce high quality metal and carbide coatings equivalent to the D – Gun process and with superior properties to conventional flame spray processes. Main Applications Rotary knife blades Aero engine parts Gate valves Pistons Shafts High Velocity Oxy-Fuel Process Description The HVOF process typically uses hydrogen as the […]

Flame Spray Wire

Wire spraying is used to apply a number of different metals and their alloys. Main Applications Commonly used in the build up of mis-machined parts; for applying corrosion resistant coatings to steelwork and as a bearing material. Flame Spray Wire Process Description A wire spray gun uses oxygen and acetylene to produce a flame through […]

Flame Spray Powder

Flame spraying is primarily used to apply abradable coatings or nickel/chrome self-fluxing alloys which are subsequently heat treated in order to metallurgically bond them to the substrate (Fused Coatings). Main Applications Abradable coatings are used for machine element clearance in gas turbine compressors. Fused coatings are extensively used in high wear applications such as mining […]

Biomedical

The PLASTALLIUM™ system holds benefits for CEMENTED and CEMENTLESS fixation applications and is employed regularly in both approaches. The surface topography of PLASTALLIUM™ 212 is ideal for mechanical interlocking of cement or bone. In the latter case, an additional coating layer of bio-conductive material (e.g. CAPTAL™ Hydroxyapatite) is employed to promote apposition of good quality […]
