Wear Resistant Coatings protects against a range of different abrasion related failures. Wear is a phenomenon that can arise through different mechanisms in severely different operational environments:
- Abrasion – caused by particles or protrusion on a surface have constant sliding contact with surface subjected to wear
- Erosion – surface degradation process which occurs due to the impact of external particles on the surface of a materials
- Fatigue – surface degradation process caused by contact between roughened surface with very high local stress during sliding or rolling
- Fretting – destructive phenomenon that occurs between two surfaces in contact when they experience small oscillatory movements
- Corrosive Wear – surface degradation process caused by a chemical reaction and mechanical action between the material surface and the corroding medium

Applications
The requirement for wear resistant coatings permeates most industry sectors, where the list of applications that utilise wear resistant coatings is virtually endless. The application of coatings that protect against wear often protect against other failure modes including corrosion and erosion. A range of different applications across different industrial sectors is summarised below:
- Aerospace – Combustor Components, Transition Liners, Blades, Vanes, Nozzles
- Industrial Gas Turbine – Combustor Components, Transition Liners, Blades, Vanes, Nozzles
- Oil & Gas – Radial Bearing, Mud Rotors, Mandrels, Piston Rods, Sleeves, Antennas, Torquers, Drilling Tools, Shafts, Mud Pump Plungers, Pins, Christmas Tree Components, BOPs, Riser Systems, Valve Casing, Butterfly Valve Discs, Balls, Plugs, Seats, Choke, Orifice Plates, Guides, Rings, Stems, Pump Casing, Pump Plungers, Rotors, Impellers, Hydraulic Cylinders, Fin Fan Heat Exchangers, Ducting & Pipework, Storage Tanks
