Surface Preparation

Poor results of an electroplating procedure can often be traced to one factor-the failure to properly prepare the substrate surface, which is the cornerstone of successful electroplating, ensuring that the final finish meets the set standards for both appearance and performance. Contaminants such as dirt, grease, oil, rust, chemicals, and other foreign materials can interfere with coating adhesion, durability, and continuity. Therefore, various preparatory techniques, such as degreasing, pickling, etching, and surface roughening, are utilized to overcome these challenges. These steps not only purify the substrate surface but also create an optimal topography for electroplating. With many years’ experience in metal processing, you can trust the experts at Alfa Chemistry to provide the most appropriate surface preparation method for your projects and budgetary requirements.

Surface preparation process

Our surface preparation process is a three-step process consisting of pre-cleaning, secondary cleaning and surface activation.

Significance of surface preparation in electroplating

Understanding the role of surface preparation is indispensable for those looking to achieve the full benefits of electroplating while upholding the highest quality standards. The significance of surface preparation in electroplating mainly encompasses the following key points.

Adhesion: In order to achieve a high-quality, durable electroplated coating, it is imperative to address contaminants such as oils, grease, oxidation products, or residues that may hinder adhesion between the substrate and the electroplated coating. This underscores the critical importance of thorough surface preparation prior to engaging in the electroplating process.

Longevity of the electroplated coating: The longevity and performance of electroplated coatings are significantly influenced by the thoroughness of surface preparation. A well-prepared surface leads to a robust electroplated coating that can resist environmental factors and mechanical stress, increasing the component’s lifespan and reducing the need for repairs or replacements.
