Moreover, thanks to its electrically neutral stabilization, it helps prevent contact corrosion. One of the world's largest suppliers of automotive components, Germany's Robert Bosch GmbH, is using the new material in a fan module for several international automakers.
Unlike traditional contact corrosion inhibitors, VpCI 's have a moderately high vapour pressure that allows them to function in the vapour phase without applying VpCIA directly to the metal surface.
In order to avoid so-called "contact corrosion," extensive tests were performed to eliminate unfavorable material combinations.
It allows dissimilar materials to be joined, saves weight, seals joints and forms an insulating film to prevent contact corrosion. Low pressure moulding proved a popular feature at last year's Southern Manufacturing Show and in 2014 Henkel will again be emphasising its merits.
While [Fe.sup.3+] concentration in the water is increased, the copper contact corrosion rate intensifies.
Applications of a Real-Time Electronic Contact Corrosion Monitor, Proceedings of Advances in Instrumentation and Control Vol 46: pp 929-955.
In developing its Monomet cylinder head gasket, STE of Wilhelmshaven, Germany, used a powder coating compound of Victrex PEEK polymer and PTFE (polytetrafluoroethylene) to prevent micro abrasion, contact corrosion, and "welding" of the cylinder head to the cylinder block.
This metal and salt-free stabilizer ensures there is no contact corrosion.
The material is said to have outstanding dielectric properties; it achieves flammability compliance without contact corrosion problems, and the blocks are also resistant to chemicals commonly encountered in the service environment.
