Abstract: The present disclosure refers to an electrochemical method for the indirect monitoring of the concentration of the active matter of scale inhibitors, composed of phosphonates, based on principles of advanced oxidative processes, which is viable for quality control of scale inhibitors in onshore and offshore installations. Additionally, the present disclosure refers to an electrochemical system for the indirect monitoring of the concentration of the active matter of scale inhibitors in onshore and offshore installations.

Abstract: Methods and systems for painting surfaces (especially vehicle surfaces such as exterior aircraft surfaces) are provided whereby an applied basecoat layer may be treated with plasma (e.g., a non-thermal atmospheric pressure plasma) or laser radiation so as to form a treated basecoat layer which exhibits a decreased contact angle and an increased wetting energy as compared to the contact angle and wetting energy of the basecoat layer which is untreated. At least one inkjet printed color layer may be applied onto the treated basecoat layer followed by the application of a clearcoat protective layer over the one or more inkjet printed color layers.
