文摘

Cathodic arc evaporation of Al-Ni is demonstrated for different target compositions. Target surface versus coating compositions are given for reactive and non-reactive modes. We show that both oxide and Al-Ni intermetallics can be formed in a single process. The progressive oxide scaling during annealing of Al-Ni and Al-Ni-O coatings is discussed.
