Abstract

Corrosion costs are still huge, reaching up to 1% from gross national product of many industrial countries. From other side, society cannot develop further without considerable saving in energy and materials, and better protecting our environment. Transferring these demands into the coatings world means that the coatings must be as thin as possible and produced by energy and environment saving technologies. Thin and ultrathin coatings have several naturally positive properties as compared with the traditional, thick protective coatings: better elasticity and optical transparency, smaller residual stresses, etc. But thin coatings must be still well protective, wear resistive, and if needed, paintable and/or biocompatible. For development of thin protective coatings, several techniques were used, e.g. atomic layer deposition, ALD, for preparing nanolaminates of metal oxides and electrophoresis for nanographene ultrathin films, and anodizing plus ALD for new thin protective coating applicable for anodizable alloys; the latter technology is widely patented. In the presentation, results of laboratory studies, tests will be presented, first introductions of the methods into industry will be reviewed, and perspectives of further developments will be discussed.
