Abstract
Chromate conversion layers are widely used in various industrial process in order to create performant protective layers. In order to improve the quality of these layers, various analytical techniques were used to understand the deposition mechanism of these films. Unfortunately, it is rather difficult to understand all the subleties and for that reason we propose to couple EQCM measurements with inductively coupled plasma (ICP) analysis. The same zinc sample dipped in a classical chromate conversion bath was examined. Various parameters were obtained by this way such as the corrosion rate of zinc or the film formation rate. An identification of the film was also obtained by estimating the molar mass of the elements.
