AntiCorr® is an anticorrosion coating which is applied to various metals in the atmospheric pressure plasma.
The coating is part of a range of coatings that can be incorporated into the PlasmaPlus® system.
An organosilicon compound is added to the plasma as the starting material for an AntiCorr® coating. High-energy excitation within the plasma fragments this compound and deposits it on the surface in the form of a vitreous coating. The chemical composition of the AntiCorr® coating can be varied according to the application to ensure that optimum results are obtained for any given material. The AntiCorr® coating is comparable with a low-pressure plasma coating in qualitative terms.
The decisive advantage of the AntiCorr® coating is the selective treatment with which only the desired parts of the component are treated instead of treating it completely and in places that are not necessary.
To demonstrate its effectiveness, an AntiCorr® coating was applied to AlSi12 (Fe), an aluminum die-casting alloy typi- cally used in the automotive industry. The test specimens were subject to a 720-hour test cycle under the salt-spray test conditions stipulated in DIN ISO 9227.
