For certain blades with a Pt coating, maybe, but since there are so many sizes, I would think the nozzle would have to be manually controlled. It might also be feasible to tumble them.

Most of the PMs are in the form of brazes used to braze parts together. I doubt if it would work on them.

Since the treatment only stripped the coating and not the underlying metal I would hardly doubt it would touch the surface treatments of the blades, it would be even harder to affect the brazing between metal parts.

Thanks, that was a very interesting file.

Interesting but very dated. 1966 was in the stone age of jet engine alloys. Probably the biggest change came in the 80's, with the advent of of single-crystal alloys. There are tons of more modern articles when you search for - superalloys jet engines. You might also add the word "generations" to the search.

Got this PT coated blade today , would somebody tell me how much PT coating would be there ..

Thanks

Need a photo to show the entire blade. Put something next to it to show its size - ruler, coin, etc.

look like titanium fan blades to me.

Platinum plated blades of that size are only found in industrial gas turbines and their yield is low relative to other, smaller pieces with a higher surface area to mass ratio.
