Corrosion is constantly a major problem of the world economy in the field of metal products, metal processing and other areas that utilise metals. Previously used compounds utilizing hexavalent chromium were amongst the most effective materials for corrosion protection but regulations have been recently introduced that forbid their use. Consequently, there is a huge drive by engineers, technologists and scientists from different disciplines focused on searching a new, more effective and environmentally-friendly means of corrosion protection. One novel group of materials with the potential to solve metal protection problems are sol-gel thin films, which are increasingly interesting as mitigation corrosion barriers. These environmentally-friendly and easy-to-obtain coatings have the promise to be an effective alternative to hexavalent chromium compounds using for anti-corrosion industrial coatings. In this review the authors present a range of different solutions for slow down the corrosion processes of metallic substrates by using the oxides and doped oxides obtained by the sol-gel method. Examples of techniques used to the sol-gel coating examinations, in terms of anti-corrosion protection, are also presented.
在金属制品、金属加工及其他使用金属的领域，腐蚀一直是世界经济的一个主要问题。以前使用的含六价铬化合物是最有效的防腐材料之一，但最近出台了禁止其使用的规定。因此，来自不同学科的工程师、技术专家和科学家们大力推动，致力于寻找一种新的、更有效且环保的防腐方法。一类有潜力解决金属保护问题的新型材料是溶胶 - 凝胶薄膜，作为缓蚀屏障，它们越来越受到关注。这些环保且易于获得的涂层有望成为用于防腐工业涂层的六价铬化合物的有效替代品。在这篇综述中，作者介绍了一系列通过使用溶胶 - 凝胶法获得的氧化物和掺杂氧化物来减缓金属基底腐蚀过程的不同解决方案。还介绍了用于溶胶 - 凝胶涂层防腐保护检测的技术示例。
