Abstract

Inconel 617 coatings, 10 to 13 μm thick, were r.f. magnetron sputtered on to commercially pure α-titanium substrates without external bias or heat and examined in the as-deposited condition by analytical transmission electron microscopy (TEM). Coatings were an f c c solid solution with an average lattice parameter of 0.366 nm and had a (1 1 1) preferred orientation. Examination of the microstructure in cross-section showed it consisted of columnar grains on average 60 nm wide, and contained a high density of twins and stacking faults parallel to the substrate. Comparison with sputtered copper and nickel coatings indicate that the stacking fault energy of sputtered Inconel 617 is similar to that of pure copper. © 1990 Chapman and Hall Ltd.
