Resumo
Austenitic stainless steel is used in several industrial branches due to its mechanical and thermal properties, and
to its good corrosion resistance. With low cost and biocompatibility, it is used to manufacture prostheses and
devices for bone fixation. However, direct contact with body fluids may cause corrosion. Thin films of FeAlCr
intermetallic alloy can be used to increase service life of prostheses and avoid replacement surgeries. The aim of
this work was to cover the austenitic stainless steel to study the effect of target–substrate distance on the film
characteristics. Coatings were performed using the magnetron sputtering technique with the substrate positioned
at different distances from the target. The influence on film thickness, morphology, roughness, and adhesion to
the substrate was investigated. The thin films of FeAlCr (160 nm thick deposited at 100 mm far from the
substrate) were formed by smaller particles (11.2 nm long), densely packed (551,000 particles/mm2), with flat and
regular appearance, and greater adherence to the substrate.
