Q. Would like a summary on the process and what its benefits are, common problems and the information required by a vendor to apply the seal properly. I currently have no experience in this area and my usual contacts are just as lost as I am.

A. "Chrome seal" as the McDonnell Douglas St. Louis engineer's called it, is impregnation of chrome, similar to impregnation of castings. In the chrome seal process, the intent is to improve the corrosion prevention ability of the porous chrome plate. This process was called out frequently on their high strength steel chrome plated landing gear detail parts. A lot of these parts could not have the soft (relatively) layer of sulfamate nickel applied under the chrome for corrosion protection, so the "chrome seal" process was created. If your work is for Boeing St. Louis, your buyer can steer you to shops that can do the work, including mine.

A. My company seals chrome per PS11501. Our process cleans and impregnates porosity in the chrome surface allowing it to be used in high pressure conditions without leakage traveling through the chrome.

A. [A company in] NY, was the first to use this process, on the F-18 landing gear in 1978. Using polyester resins & thermal cure. The chrome was impregnated to provide a pressure tight seal to prevent hydraulic fluid from leaking between the chrome & retaining seal. The process also delayed the oxidation process of the chrome plate preventing pitting and providing a longer life of the chrome plate.

Ed. note: Anyone seeking to find shops to do this process for them should post their inquiry as an RFQ so they can be contacted privately. Sorry, but we cannot post public discussions of sourcing ( huh? why?).
