Surface coating


All surface technology requires the substrate surface to be pretreated. This, in turn, is dependent on several factors – for example type and composition of the base material (metals, non-ferrous metals, etc.), type and extent of impurities (unwanted separation layers) and so-called fault zones caused by processing. This occurs, for example through cleaning, greasing, staining, etching or creating conversion coats (phosphating and other chemical-thermal procedures).

Application of surface coating

Applying the material with specified properties to the substrate (material) and the production of a bond which fulfils the defined properties, for example the mechanical behaviour (firmness and toughness) is known as the application. The applied coat of material fulfils specific properties which go beyond the mechanical properties such as corrosion resistance and wear resistance, power transmission (coefficient of friction in steelwork)… right up to optical and aesthetic demands. In order to create a well functioning and operational bond, sufficient adherence (grip) of the coating is required. This is particularly relevant in the case of mechanical tension, for example due to thermal expansion. There are three different kinds of coating: metal coating, non-metal organic and non-metal non-organic coatings.

Metal coatings

Metal coatings can be coated using ECD (electrochemical metal deposition), by deposing metallic coats from the gas phase or also by hot-dipping (one of the oldest techniques of creating metallic casings – for example hot-galvanising, hot-dip tinning, hot-dip aluminising), by metal spraying (flame spraying, electric arc spraying, plasma spraying), by plating (roll cladding, explosion cladding) or also through chemical-thermal procedures (aluminising, inchromating, sheradizing).
