Co coating and CoP alloy reinforced by ZrO2 nanoparticles are prepared on the surface of brass substrate DC electrodeposition to improve magnetic property corrosion resistance. The Co/ZrO2 CoP/ZrO2 composite electrodeposited can be used in field thin-film heads, sensors electronic circuits. By comparing performance different cobalt-based coatings, influence is studied. It found that cobalt a typical irreversible process with diffusion control. comprises about 81% 19% P. However, possesses 86% Co, 3% P, 11% Zr. incorporation 15 g/L nanoparticle size 50 nm beneficial content decrease amount phosphorus coating. hardness 350 HV. 400 HV 470 HV, respectively. All coatings show cellular morphology. incorporated enter into lattice or disperse at grain boundary refine limit displacement domain resistance coercivity extremely. out has best only 9.7 μA/cm2 current density largest 665.1 Oe. optimal good promising material microelectromechanical systems as micro pumps, read motors, so on.

It remains a popular question whether rare earth oxides encourage reinforcing phases to the uniform distribution in cermet coating improve mechanical properties. This study applied laser cladding prepare TiAl/WC/CeO2 MMC coatings on TC21 alloy substrate. The effects of CeO2 content phase composition, microstructure formation, evolution mechanism, and properties were investigated. Results show that incorporation did not change composite coating, but shape TiC has close relation content. enhanced fluidity molten pool, which further encouraged TiC/Ti2AlC core-shell reinforcement phase. With increase content, optimized contributed homogenous fine grain size. Owing hard strengthening dispersion CeO2, microhardness was all significantly higher (almost 1.6 times) than Importantly, addition improved wear resistance coating. work provides certain reference value for surface key parts aerospace field.
