Chromating

The chromating process

The process involves immersing the metal in a chromate solution, with the reaction between the metal surface and the chemicals forming the chromate layer. This layer not only provides protection against corrosion, but can also serve as an adhesion layer for paint or other coatings. Chromating is widely used in the aerospace and electronics industries because of the favourable properties of the resulting chromate layer.

Benefits of chromating

• Corrosion protection: One of the main advantages of chromating is the excellent corrosion protection it provides. The process creates a thin chromate layer on the metal surface, which acts as a protective barrier against corrosive elements such as moisture and salts.

• Adhesion for coatings: Chromating improves the adhesion of coatings, such as paints and powder coatings, to the metal surface. This allows the coating to adhere evenly and permanently to the metal, resulting in a long-lasting and uniform finish. In addition, the chromate layer formed provides an effective barrier against corrosion, extending the life of the coated metal.

• Improved adhesion for adhesives: In addition to coatings, chromating also improves the adhesion of adhesives and sealants to the metal surface. This is beneficial for applications where bonding between metal components is crucial.

• Environmental friendliness: Modern chromating processes are lead-free and comply with strict environmental standards. This makes chromating a relatively environmentally friendly surface treatment option.

• Minimal dimensional change: Chromating typically causes minimal changes in the dimensions of the treated metal, which is important in precision components where dimensional accuracy must be maintained.
