Black Chroming Process. In simple terms, electroplating is achieved by passing an electric current between two electrodes which are immersed in an electrolyte bath comprising of chromic acid. The newer black chrome process plate a smoother, more reflective, dark chrome finish that does not require a post dip for corrosion protection.
Black chrome is an alternative chrome plating process that has become increasingly popular in a number of applications, including medical equipment, audio equipment and aftermarket automotive applications, where it is used on items like trim and wheels. The product of chrome plating is called chrome. Black chromium plate articles are produced by the use of a novel electroplating bath, wherein a light and heat absorbing decorative and protective electroplate is.
The Initial Patent Related To Electroplating Black Chromium, Was Issued To Gilbert And Buhman.
In principle, you clean the parts, activate them with a wood's nickel strike process, bright nickel plate them, then chrome plate them in a chrome plating solution that has been deliberately contaminated with materials that cause the deposit to be black. 1 further patents were filed by westinghouse electric in. Appearance can be very black when applied over the top of a bright nickel deposit.

When applied over a dull deposit it becomes gray in color. Next the old chrome is removed in a cold caustic bath, this time electrified to 12 volts with a reverse charge.
It Is A Combination Of Two Processes, Sputter Deposition And Powder Coat.
The black color is achieved by alloying other metals with the chromium deposit. In simple terms, electroplating is achieved by passing an electric current between two electrodes which are immersed in an electrolyte bath comprising of chromic acid. 1 gilbert and buhman developed a process utilizing aqueous chromic anhydride and acetic acid to achieve a dark gray to black deposit on rifle parts, artillery parts and military equipment at the rock island arsenal.
The Chrome Plating Process Is A Method Of Applying A Thin Layer Of Chromium Onto A Substrate (Metal Or Alloy) Through An Electroplating Procedure.
The newer black chrome process plate a smoother, more reflective, dark chrome finish that does not require a post dip for corrosion protection. As the name implies, black chrome has a dramatic dark, smoky look. The old chrome and stripped metals are not recyclable.
To Achieve The Maximum In Corrosion Resistance, Black Oxide Can Either Be Waxed Or Oiled To.
Sometimes a black chromium deposit is plated over a regular chromium deposit. Our products are trusted by professionals all over the globe; Back in the day, this new process utilized a proprietary dry method of applying metals and clear coats.
