20160024679 | TURBINE ENGINE COMPONENT WITH A DIFFUSED CHROMIUM LAYER - Turbine blades, including airfoils, of aviation or industrial gas turbine engines are treated with chromium to improve resistance to hot corrosion. Various alloys, including, but not limited to nickel, cobalt, molybdenum, and stainless steel alloys may be treated with chromium. Chromium is introduced through the surface and into the material by a process of electrolytic molten salt deposition. This treatment produces components with increased chromium content and improved resistance to hot corrosion caused by airborne sodium salts entering the turbines. | 01-28-2016 |
