chromeplated

Chromeplated describes an object finished with a chromium layer produced by electroplating. The coating is bright, hard, and provides corrosion resistance, making the finish popular for decorative purposes as well as functional components.

The typical process starts with cleaning and activating the substrate, followed by an underlayer of copper and/or nickel to promote adhesion. Chromium is then deposited from a chromium-containing electrolyte. Decorative chrome is a thin layer aimed at appearance, while hard chrome is thicker and designed for wear resistance.

Substrates commonly include steel, iron, brass, and some aluminum alloys. The coating can be applied to complex shapes with proper masking and holding fixtures, but uniform coverage requires careful control.

Chromium plating has historically used hexavalent chromium baths, which raise health and environmental concerns. Regulations limit exposure and waste, and many facilities use protective measures or shift to trivalent chromium plating or alternative coatings.

Applications include automotive trim, plumbing fittings, tools, hardware, and various industrial components where a hard, smooth surface is beneficial.

Care and repair involve avoiding damage to preserve the coating; cracked or worn chrome may be refurbished or re-plated by professionals.
