Chromic acid anodize was used as part of the passive thermal management system for LDEF. The anodize process used for LDEF structures was actually a modification of the standard chromic acid anodize process, as specified by MIL-STD … WebBoric-Sulfuric Acid Anodize (BSAA) is an alternative to chromic acid anodize. Primary applications include aircraft and aerospace components. It is used for corrosion protection and paint adhesion. Paint adhesion is equal or superior to chromic acid, and the process is more energy-efficient than chrome-based processes.

WebFeb 16, 2024 · Chromic acid anodizing, or Type 1 anodizing, is an electrochemical process that is used as a protective treatment for aluminum. During this process, chromic acid is used to form an amorphous, corrosion-resistant layer of aluminum oxide. WebChromic acid anodize is used for optimum corrosion resistance for severe applications, such as aerospace and military use, but because chrome, in some form, is a carcinogen this process is being phased out. … WebThe chromic acid bath uses stainless steel cathodes at a cathode to anode ratio of 1:5. The 3 % bath is operated at 104º F while the 10% bath operates at 129º F. The average current density is about 3 amps per square foot (3 asf). If the parts are to be inorganically colored, the anodizing time should be restricted to less than 30 minutes. gardeners customer service
