Abstract: To study the aluminium diffusion coating of copper, pure copper plates were calorized by a conventional pack cementation method using a Fe-50%Al alloy powder as a source of aluminium. A thin layer of α-Cu was formed on the copper substrate, followed by a thick αーCu+γ2 (Cu9Al4) eutectoid layer with floating α-Cu particles, and γ2 particlds near the surface of the diffusion layer. The Fe-50%Al alloy powders adhere to the sample and are embedded into the diffusion layer. Oxidation test of the calorized copper shows that the aluminium diffusion coating used improves the oxidation resistance of copper, even by a lowest temperature and a shortest time coating studied.
