Abstract

The activity of CIDETEC Surface Engineering Institute is focused on the application of surface technologies for the improvement of materials properties (corrosion, tribology, aesthetics, etc.) and the development of new multifunctional coatings among others, using the electrophoretic deposition technology. In this field, the investigation is aimed at improving endurance (corrosion resistance and mechanical properties) as well as adhesion and other specific properties of e-coatings (e.g. organic, ceramic …) over several substrates (e.g. metals, light alloys …) using the EPD.

The CIDETEC institute for Surface Engineering is a reference institute and the main thrust of an innovation pole specialising in the development of these technologies, providing surface solutions throughout the entire value chain for the automotive, aerospace, power generation and other sectors.

Our developments not only rest at laboratory testing, but we also have the possibility of scaling-up these processes. The pilot line of CIDETEC has a capacity of a complete line for pre-treatment processes (e.g. degreasing tank of 220 L, pickling of 150-180 L and several rinsing stages of 150-180 L). The e-coating system itself has a capacity of 400 L of product divided in two tanks; one of them is for the e-coating application (220 L) and the other for product recirculation (180 L). In addition, an ultrafiltration unit and permeate tank are part of the e-coat system (145L). DC and PC power supplies are used in the line (200 V/50 A and 300 V/15 A) as well as a versatile titanium jig to coat several panels’ dimensions and fill size prototypes of demonstrators to achieve TRL5 levels (“technology validated in relevant environment”).
