Sometimes the component has a conforming anode made from lead/tin or platinized titanium. Sometimes the component enters the chrome plating vat while electrically live. Ferric chloride is also popular for the etching of nimonic alloys. Different substrates need different etching solutions, such as hydrochloric, hydrofluoric, and sulfuric acids. There are many variations to this process, depending on the type of substrate being plated. Application of plating current for the required time to attain the desired thickness.Immersion in the chrome plating bath, where the part is allowed to warm to solution temperature.Rinsing (not necessary if the activation and plating steps are done in the same bath).Removal of remaining organic contaminants using emulsion cleaning, alkaline cleaning, anodic electrocleaning, or solvent cleaning by immersion, spray, manual application, or vapor condensation.Manual cleaning to remove dirt and surface impurities.The preparation and chrome plating of a part typically includes some or all of these steps: Some fume suppressants used to control the emission of airborne chromium from plating baths are also toxic, making disposal even more difficult. In most countries, their disposal is tightly regulated. Sometimes, a less expensive substitute for chrome such as nickel may be used for aesthetic purposes.Ĭhromium compounds used in electroplating are toxic. ![]() The chromium layer can be decorative, provide corrosion resistance, facilitate cleaning, or increase surface hardness. A chrome plated part is called chrome, or is said to have been chromed. Decorative chrome plating on a motorcycleĬhrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. Not to be confused with Chromate conversion coating.
