Cladding

Change of surface properties

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

Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
