To date, Fe 70 Pd 30 alloy films have been produced by both physical and (electro)chemical methods. Gold thin films can be deposited on other materials, where they are used. Cerium oxide based coatings from ∼100 to ∼1400 nm in thickness were deposited onto Al 2024-T3 alloy substrates by magnetron sputtering of a 99. Here, δ can be defined from the below equation: (3) where n is the number of elements, z is the molar fraction of the ith element, r is the atomic radius of the i th element, and is the mean atomic radius. 4 T. The sputtering yield ratio S(Au)/S(Pd) was found to be 1. Melting points of common materials.
