Welcome To AMC's Web Page Highlighting Diffusion Coatings.
Diffusion coatings - typically Plainum Aluminides, Aluminides, Siliciding and Chromizing have found a good use for application to nickel and cobalt based super alloys used in aerospace components as well as industrial turbine components (used for power generation). These coatings can enhance resistance to oxidation and sulfidation which can shorten the life of the component with disastrous results.
Where else have diffusion coatings found acceptability?
Petrochemical cracking towers and general components have also demonstrated a need for protective coatings - typically chromizing, siliciding and aluminizing - sometimes alone and sometimmes with two or three elements co-diffused.

Areas of expertise
We can assist in all phases of diffusion coating application - including assistance in setting up a noble metal (Platinum) plating facility as well as the thermal processing needs for diffusion of Aluminum, Chromium and Silicon. These can be accomplished using either CVD (Chemical Vapor Deposition), Pack (where the part is essentially buried in the aluminum, chrome or silicon bearing precursors with a predominance of an inert material such as alumina "sand" and a activator, as well as another process called "atp" or "above the pack" gas phase diffusion coating.

Advantagesof CVD and Gas Phase
To coat the "internals" of components - both blades and vanes, gases can be generated in numerous ways and then passed into the component - and given the correct conditions of time, temperature and gas concentration can result in the desired element(s) diffusing into the component.
