- Service life:
- Lets a part or component operate while keeping its mechanical properties and performance in an environment where, without a protective layer, it could not survive.
- Wear agent:
- Liquid, solid or gaseous substance with corrosive attack
- Attack effect:
- Oxidation or corrosion of the substrate
- Layer description:
- Protects the coated part / area to prevent or delay chemical corrosion / oxidation.
- Layer application:
- Usually by design, application is recommended at the manufacturing stage. Later, while the component is in use, the layer can be replaced as it degrades—without replacing the coated component—if done in time.
- Material type:
- The material is selected according to its behavior against the medium causing the attack. For example, with sulphuric acid present, an acid-resistant material is chosen, such as Aluminum (metal) or Aluminum oxide (ceramic). Atmospheric corrosion: Aluminum, Zinc–Aluminum. Corrosion in salt / fresh water: Aluminum, Zinc–Aluminum, Zinc. Corrosion by salts: ceramic compounds, nickel-base superalloys, etc.
- Typical location:
- Exposed areas
