Composite cobalt-based alloy for functional coatings deposition using heterophase transfer
https://doi.org/10.22349/1994-6716-2019-98-2-57-63
Abstract
The paper describes an alloy with a content of 20–26% Co, 17.4–21.1% Cr, 2.6–4.9% Si, 3–5% Re, 4–6% Zr, 0.2–0,6% Ce, 0.1–0.5% La, 0.3–0.7%Y, 2–4% Al. The cobalt-based alloy is applied as protective coating on components of precision engineering with adhesion 42–45 MPa, microhardness 3.6 GPa, corrosion resistance class 1, within the range of operating temperatures from –60 to 550°С.
