By depositing PVD coatings on already conventionally galvanized steel sheets novel zinc alloy coatings have been developed. One of the biggest advantages of PVD coatings lies in the broad choice of coating materials as there are no constraints due to chemical reactions between the substrate and the coating. This leads to a variety in the coating compositions. Accordingly, PVD processes enable customized solutions for various purposes. Magnesium on galvanized sheet steel has been identified as a very promising coating system. Corrosion performance is improved considerably while other properties like forming, joining and painting are comparable to or better than the untreated galvanized material.%Des nouveaux revetements d'alliages de Zn ont ete developpes par depot PVD sur des toles minces galvanisees, Lun des principaux avantages du PVD reside dans la gamme tres large de depots realisables, grace a l'absence de contrainte liee a la compatibilite entre le depot et le substrat. Ceci permet de realiser une grande variete de revetements. De ce fait, le PVD permet de proposer des solutions 《a la carte》 pour differentes applications. Le depot de magnesium sur des toles galvanisees presente de nombreux avantages. La resistance a la corrosion est tres fortement amelioree, alors que l'aptitude a la mise en oeuvre des toles par formage, assemblage ou laquage est maintenue ou amelioree par rapport a celle de la tole simplement galvanisee.

机译：通过将PVD涂层沉积在已经常规镀锌的钢板上，已经开发出新颖的锌合金涂层。 PVD涂层的最大优势之一在于涂层材料的广泛选择，因为不受基材和涂层之间化学反应的限制。这导致涂料组合物的变化。因此，PVD流程可实现用于各种目的的定制解决方案。镀锌钢板上的镁被认为是非常有前途的涂层系统。腐蚀性能得到显着改善，而成型，连接和涂漆等其他性能可与未处理的镀锌材料相媲美或优于未镀锌的材料。 PVD可以在大型仓库中变现，在仓库和基础设施之间建立一个不存在的矛盾。 Ceci permet de Realiser和Grande Varete de Revetements。根据《点菜》解决方案的建议，PVD性能得到了充分的体现。镁制超长效电镀厂具有无与伦比的优势。具有抗腐蚀，抗腐蚀和抗腐蚀的作用，还具有一定的抗腐蚀能力，可将抗腐蚀的抗氧化剂和抗氧化剂的组成与抗腐蚀能力相提并论。
