Molybdate anions are used as an individual inhibitor or in mixed synergistic combinations added directly to the solution, incorporated as fillers, pigments or nanocontainers into various coatings (sol-gel, anodised, plasma electrolytic, organic and layer double hydroxide coatings), as an agent in pre-treatments or post-treatments or as individual conversion coatings prepared to be exposed to aggressive media. The review addresses the action of molybdate on aluminium alloys in each of these applications. The general chemical characteristics of molybdenum are described with a particular emphasis on aqueous chemistry and the formation of monomer and polynuclear species.

钼酸盐阴离子用作单独的抑制剂或以混合协同组合形式直接添加到溶液中，作为填料、颜料或纳米容器掺入各种涂层（溶胶-凝胶、阳极氧化、等离子电解、有机和层状双氢氧化物涂层）中，作为试剂在预处理或后处理中或作为准备暴露于侵蚀性介质的单独转化涂层。该综述讨论了钼酸盐在每种应用中对铝合金的作用。描述了钼的一般化学特性，特别强调水化学以及单体和多核物质的形成。
