Abstract Organosilane coatings are widely used as adhesion promoters, anti-adhesive and corrosion protective layers. Although they provide high stability, the harsh conditions during industrial applications lead to damage of the applied coatings over time. In this study, a simple and rapid method for the renewal of worn and damaged organosilane coatings was established. Steel surfaces were coated with a perfluorinated and a dipodal organosilane in order to introduce anti-adhesive properties to the substrate. The applied organosilane coating was removed via flame treatment, which simultaneously activated the substrate surface for recoating with another silane layer. The proposed mechanism was confirmed employing contact angle measurements and X-ray photoelectron spectroscopy. Moreover, it was shown that the quality and performance of the primary and the secondary coatings were comparable regarding to their anti-adhesive properties and chemical composition as well as surface roughness and thermal stability.

在金属基材上修复防粘有机硅烷涂层的简单快速方法

摘要 有机硅烷涂料被广泛用作增粘剂、防粘剂和腐蚀保护层。尽管它们提供了高稳定性，但工业应用过程中的恶劣条件会随着时间的推移导致所应用的涂层损坏。在这项研究中，建立了一种简单快速的方法来更新磨损和损坏的有机硅烷涂层。钢表面涂有全氟化和双足有机硅烷，以便为基材引入抗粘连性能。通过火焰处理去除施加的有机硅烷涂层，同时活化基材表面以重新涂覆另一硅烷层。采用接触角测量和 X 射线光电子能谱证实了所提出的机制。而且，
