Abstract

SummaryNiobium is well known for its chemical stability and excellent corrosion resistance which is based on the formation of a stable oxide layer of Nb205 in aqueous media It therefore finds wide application in areas where chemical stability is important, such as in chemical engineering equipment. Disadvantages of Nb are its high material costs and the fact that it is not possible to deposit Nb by the rather economic technique of aqueous electrodeposition. However, other deposition techniques such as physical vapour deposition may be used to produce niobium coatings. Due to its high melting point, sputtering is the preferred PV D deposition technology.Improved corrosion resistance approaching that of bulk Nb was found for lμm thick Nb coatings on 304 stainless steel substrates The corrosion performance very much depends on the method of ion etching prior to deposition. Microstructure, texture and microhardness as well are strongly influenced by the type of ion etching pre-treatment and by the temperature...

定向电弧/非平衡磁控管复合沉积制备耐腐蚀Nb涂层

摘要铌的化学稳定性和优异的耐腐蚀性是众所周知的，这是建立在Nb205在水介质中形成稳定的氧化层的基础上的，因此在化学稳定性很重要的领域得到了广泛的应用，例如在化学工程设备中。铌的缺点是材料成本高，而且不可能通过相当经济的水电沉积技术来沉积铌。然而，其他沉积技术如物理气相沉积可用于生产铌涂层。由于其高熔点，溅射是首选的PV - D沉积技术。在304不锈钢基体上制备了厚度为lμm的铌涂层，其耐蚀性能提高到接近大块铌的水平，其腐蚀性能在很大程度上取决于沉积前离子腐蚀的方法。显微组织、织构和显微硬度受离子蚀刻预处理类型和温度的强烈影响。

期刊介绍： Transactions of the Institute of Metal Finishing provides international peer-reviewed coverage of all aspects of surface finishing and surface engineering, from fundamental research to in-service applications. The coverage is principally concerned with the application of surface engineering and coating technologies to enhance the properties of engineering components and assemblies. These techniques include electroplating and electroless plating and their pre- and post-treatments, thus embracing all cleaning pickling and chemical conversion processes, and also complementary processes such as anodising. Increasingly, other processes are becoming important particularly regarding surface profile, texture, opacity, contact integrity, etc.
