Wear Resistant Coatings
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
