Components in the interior of vehicles are not exposed to corrosive stresses to such an extent. It is important in this area to ensure the functionality of parts that in use on a daily basis.
The belt buckle serves to receive and secure the safety belt system. As a safety-relevant component, they need to display good sliding properties to ensure no malfunctions when in use.
Clips are used in numerous areas to secure cable routing. They are frequently produced from high-tensile spring steel and are subject to a wide range of requirements such as sliding properties, to enable easy movement of cables. In contrast, other surfaces with a high static friction have a high pull-out strength that keeps the components together.
DÖRKEN offers a series of proven and capable micro-layer corrosion protection systems for the coating of components in the interiors of truck cabs. Where there are low requirements of corrosion protection a topcoat coating with specific functional characteristics such as glide or friction properties is often suitable. In other cases special systems consisting of a zinc flake base coat and a topcoat can be applied, depending on the parts concerned. The very thin coats cross-link at comparatively low temperatures-without generating hydrogen in the process. This means that there is no risk of application-related, hydrogen-induced stress corrosion cracking. A further key advantage of the zinc flake systems is dry lubrication. The dry lubricating film generated by the application displays excellent friction and wear characteristics and ensures good grip in the interior.
