PROCESS DESCRIPTION
The aim of coating construction components is to create surface properties that the base material does not have. Important characteristics include:
- Corrosion resistance
 - Wear resistance
 - Thermal or electrical resistance or conductivity
 - Optical properties
 
Often it is metals that are coated. Here methods are used whose principles of operation are known from joining technology, such as:
- Soldering
 - Electric arc welding
 - Shield gas welding,
 - Plasma-powder welding
 
For heat sensitive or non-metallic components special processes have been developed, such as:
- Thermal spraying
 - Vacuum-coating
 - Electro- or immersion bath-galvanisation
 - Chrome plating
