Properties and pretreatment requirements of aluminum and its alloys
Atotech aluminum pretreatment solutions
Besides the contamination of the plating bath with manufacturing residues incorrectly performed pretreatment can lead to patchy or incomplete coating, poor bonding of a coating to the base material, pitting and blistering up to peel-off effects that can result in poor performance or low corrosion resistance of the final part.
Preparing parts made from aluminum alloys requires several pretreatment steps that provide thorough cleaning to remove oils, grease, smut, and oxides and to treat any surface modifications to create a uniform surface for the best quality of subsequent plating and coating layers.
Our pretreatment technologies optimally prepare aluminum parts for subsequent finishing operations like electroless and electrolytic plating and enhance its surface to ensure good adhesion and quality of the deposited metals. Our range of proven cleaners and pretreatment processes is designed to provide the best plating/coating quality over a long operating time and for diverse substrate materials.
