Chromium plating companies12/30/2023 During the flow of electricity between the two electrodes, chromium atoms are deposited in a layer on the electrode to be plated. One of the electrodes will be the substrate which is to be coated. Simply put, electroplating is accomplished by running an electric current between two electrodes that are submerged in a chromic acid-based electrolyte bath. The chrome plating procedure uses an electroplating process to deposit a thin layer of chromium onto a substrate (metal or alloy). Now, chrome plating is an electroplating technique used to add chromium to the surface of other metals to give them better resistance to corrosion and other harsh service conditions. Hence the metal added forms a protective shield to the base metal. chromium, nickel) have better resistance in these conditions and can be used to protect metals that are deployed in these conditions giving rise to a phenomenon called electroplating.Įlectroplating is the process that adds the surface layer of a metal to another type of metal. These damages may result in more frequent replacements and increased maintenance costs. ![]() The damages in this application go beyond cosmetic or aesthetic issues and will contribute to weakening the structural integrity of the steel deployed. This exposes it to a very harsh corrosive environment, which could lead to rust and eventual damage. For instance, one of the applications of steel is in the aerospace industry. However, most of these metals are deployed in harsh service conditions, gradually depleting their properties and adversely affecting their ability to deliver in service. This fact is owing to their desirable properties, which help them deliver when deployed in various applications. Metals like steel, titanium, aluminum, etc., have critical design and structural applications in engineering. Using best practice plating technology, Valence Surface Technologies provides numerous plating services: We offer integrated honing and grinding capabilities to complement our cadmium and chrome plating. ![]() With unique selective plating and precision masking techniques for critical plated components, we are the leading plater for satellite and UAV applications, including a proprietary process for precision internal plating of waveguides. Valence is the industry leader in quality for precision components in the aerospace, satellite, and electronics and medical device industries. Valence upholds a superior quality management system throughout the metal finishing process.ĪS9100 & NADCAP Approved P lating Services Reliability, precision, and the use of proper materials is crucial. The electroplate is used for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, or for radiation shielding.Īerospace plating is essential to the livelihood and growth of the industry. The automotive specification calling out Dusk Chrome is a combination of a satin nickel coating and a black chrome finish.Plating is a surface covering in which a metal is deposited on a conductive surface. Each of these plating combinations will develop a different appearance from a bright shiny black to a dull matte black finish. The main advantages of the newer black chrome plating processes are that they do not need to be waxed or oiled to improve the final metal finish.īlack chromes can be plated over bright nickel, satin nickel, or dull nickel. This metal plating process provides better coverage of the entire part. The newer black chrome process plate a smoother, more reflective, dark chrome finish that does not require a post dip for corrosion protection. The black color is achieved by alloying other metals with the chromium deposit. Newer black chrome plating processes have been developed from a trivalent chrome process. The finish may be waxed or oiled to improve the final appearance. The finish can be a lustrous, semi-lustrous or a matte. The appearance of the black chrome finish depends on the nature of the substrate and the surface treatment prior to electroplating. This extraordinary black chrome finish provides a hard surface, which possesses corrosion and wear resistant characteristics. ![]() ![]() The black chrome finishes were used on non-reflective surfaces and usually required a post-dip in a oil solution for the metal finishing portion.īlack chrome is usually electroplated over bright nickel or dull nickel in the same manner as decorative chrome. Developed by Allied Chemical in the 1960’s, the early black chromium deposits were hard and more textured than decorative chrome. Black Chrome Plating Black Chrome Plating Suppliers to a Wide Range of Industriesīlack Chrome has been in existence for over 50 years.
