Abstract

Tungsten alloy coatings with iron group metals (Ni, Fe, Co) are considered as advanced materials for various surface engineering applications. Such coatings should be resistant to mechanical and corrosive damage, and to have improved functionality and durability. Accordingly, the objectives of this review consist in a comparative study of available literature on corrosive and wear behavior of electrodeposited tungsten alloys with iron group metals, including our recent results on evaluation of electrodeposited Co-W coatings. The wear and corrosion resistance of Ni-W, Fe-W and Co-W strongly depends on the chosen deposition conditions and subsequently on tungsten content and structure of obtained protective coatings.
