“Background Tungsten-based alloys with iron group metals (Ni and Co), particularly CoW and CoNiW, possess better functional properties and in our case alloys were formed by electrochemical deposition. These alloys can be used as thermo-resistant Resminostat and hard-wearing materials [1, 2] and as alternatives to chromium coatings [3]. Tungsten-based alloys can be found in hydrogen power engineering, sewage sterilization, and

toxic waste putrefaction [4]. Thin magnetic films based on CoNiW alloys are promising as materials for perpendicular or near-perpendicular magnetic recording Necrostatin-1 molecular weight because of their columnar structure with perpendicular magnetic anisotropy [5–7]. Researchers are interested in these films because of their wide range of magnetic properties that are dependent on deposition conditions and chemical composition [4–6, 8–10]. It is well known that the alloy structure of CoW-CoNiW-NiW may be nanocrystalline or amorphous depending on the composition and preparation conditions [7–14]. At the same time, the degree of order of the structure significantly changes depending on the processing history of the alloy. One simple treatment, low-temperature annealing, is interesting from a practical perspective.
