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
