Typically, pure niobium oxide coatings are deposited on metallic substrates, such as commercially pure Ti, Ti6Al4 V alloys, stainless steels, niobium, TiNb alloy, and Mg alloys using techniques such as sputter deposition, sol-gel deposition, anodizing, and wet plasma electrolytic oxidation. The relative advantages and limitations of these coating techniques are considered, with particular emphasis on biomedical applications. The properties of a wide range of pure and modified niobium oxide coatings are illustrated, including their thickness, morphology, microstructure, elemental composition, phase composition, surface roughness and hardness. The corrosion resistance, tribological characteristics and cell viability/proliferation of the coatings are illustrated using data from electrochemical, wear resistance and biological cell culture measurements. Critical R&D needs for the development of improved future niobium oxide coatings, in the laboratory and in practice, are highlighted.
通常，纯氧化铌涂层通过溅射沉积、溶胶-凝胶沉积、阳极氧化和湿式等离子体电解氧化等技术沉积在金属基底上，如工业纯钛、Ti6Al4V合金、不锈钢、铌、TiNb合金和镁合金。文中考虑了这些涂层技术的相对优点和局限性，特别强调了其在生物医学领域的应用。展示了各种纯的和改性的氧化铌涂层的性能，包括涂层的厚度、形态、微观结构、元素组成、相组成、表面粗糙度和硬度。利用电化学、耐磨性和生物细胞培养测量的数据，展示了涂层的耐腐蚀性、摩擦学特性以及细胞活力/增殖情况。文中强调了在实验室和实际应用中，开发未来改进型氧化铌涂层的关键研发需求。
