aluminizing 304
(OP)
i have been searching for a typical diffusion coefficient for an aluminium powder into 304 SS can anyone help?

RE: aluminizing 304
304ss, iron-base alloy, therefore the diffusion coefficient will be influenced predominantly by iron versus other alloying elements like Cr and Ni. In reality, the diffusion coefficient for Al in 304ss will be influenced by solute alloy additions like Cr and Ni – however, this becomes very complicated in dealing with ternary diffusion coefficients.
The diffusion coefficient for Al in iron ranges from
4 x 10^-9 to 3 x 10^-8 cm^2/sec for temperatures 875 deg C to 1100 deg C

RE: aluminizing 304
I was trying to locate Alon Technologies but they went under and bought by Group Ultra, Houston no further information. There are a lot of papers around but they are hard find in all the commercial stuff popping up in search
Here is all the information that I have at the present.
