We have developed coating solutions to meet unique requirement of each application and environmental conditions.
– Wear resistance
– Corrosion resistance
– Cavitation resistance
– Thermal Barrier
– Anti-galling
High Velocity Oxy Fuel (HVOF)
Is a system usually use to produce coating resistance for wear, corrosion and cavitation since HVOF produces a very dense coating (porosity less than 5%)
Tungsten carbide is an especially effective as wear resistant coating, it offers exceptionally high hardness levels.Tungsten carbide is highly resistant to extreme temperatures below 650°C and corrosion.
Chromium oxides are also very hard and are very resistant to chemical attack so it can be an ideal solution when wear and corrosion are both present.
Chrome carbide has been an alternative use for hardchrome plating in many applications.
Plasma Spray Coating
By combining higher temperature, higher energy heat source with high particle velocity (200 – 300 m/s), the Plasma Coating produces higher and better quality.
Because of the higher heat source, the Plasma system is able to spray very high melting point materials such as ceramics like zirconium. Plasma spray coatings probably accounts for the widest range of thermal spray coatings and applications and make this process the most versatile.
One of the common uses of a Plasma system is to coat thermal barrier coatings. With demands for more fuel efficiency and higher power, the combustion sections of the aero-engines and gas turbines of power plants are stressed to increase the operating temperature. The increase in combustion temperatures are approaching the designed limits of super alloys or single crystal blades of which the turbine components are made off. By applying thermal barrier coatings on these hot path sections enables the turbines to oper
ate at a higher temperature needed by reducing the temperature of the substrate exposed.
Abradable coating are used in the compressor or turbine sections where a minimal clearance is needed between the blade tip and the casing.
Abradables are no longer restricted to aero-engines. They can be used in most rotating machinery such as stationary gas turbines, turbo compressors, radial compressors, turbo chargers, and pumps.
