Polycarboxylic acid, a scale control inhibitor has demonstrated adsorption properties on stainless steel surfaces. An electrochemically-based technique has been used to assess the extent of film formation. Calcium concentration in the solution and the cathodic electrochemical activity at the metal surface have been shown to enhance the inhibitor film formation by promoting the transport and adherence of the inhibitor. Practical implications of this findings are discussed.
