Helicopterjunky,
Thanks for the input. I do have vacuum furnaces available to me. Do you have more details you can give on how to cause alloy depletion in vacuum? I prefer to use vacuum over oxidizing atmosphere.
Yes I need to actually create a sample that exhibits alloy depletion using a Ni-based superalloy material (Mar-M 247 for example if you're familiar with the more common ones)
Yes this is for gas turbine hardware. The only details I can give is that for our lab to receive a certain approval they must have alloy depletion samples in-house (possibly for training or reference material). So as the metallurgist on staff I've been given the task of producing these...
I need to create some samples that exhibit alloy depletion in Ni-based superalloys. I've looked all over online and in my ASM Handbooks and can't find any general info on alloy depletion. I'm a metallurgist, so I know in general what it is. But I need more specifics if going to generate my...
I'm trying to prove metallurgically which metal is more brittle during impact - Nickel or Aluminum. I've located some mechanical properties data, and it shows Al has a Elongation % of 50-70 while Ni is only 30%. It lists the Young's Mod of Al at 67 GPa and Ni at 207, which would make Ni a...
I'm looking for a vendor to purchase aluminum source material for a coating process. I'd like the aluminum to be alloyed with another material such as cobalt or chromium, in chunklet form. Any suggestions?
In order to get a magnetic stainless steel you'll have to get a 400 series, such as 410SS or 416SS. Their Fe contents are above 50% which allows them to be attracted to a magnet. The 300's are less than that and are not magnetic. Visit www.suppliersonline.com - you can look these metals up here.
Pertaining to aircraft engine coatings, what are the definitions of inward coating and outward coating? What are the characteristics of each - microstructure/function? How is each formed?
Any information offered on inward vs outward coatings is appreciated.
I'm a young materials engineer working on the development of an aluminide coating process for aircraft engine components using simple CVD. I'm trying to look 10 years ahead and I wonder is the job of a coatings engineer one that can always be employed? Is it so focused that the supply of...
