Abstract: An Al2O3-coated co-deposit including an Ni-based alloy substrate, an exterior layer present on a surface of the substrate, wherein the exterior layer comprises NiCrAlY or NiCoCrAlY particles with a diameter of 0.5-50 ?m, Ni nanoparticles with a diameter of 0.1-10 nm in the form of a matrix, and Al2O3 particles that are present on the exterior surface of the exterior layer. A method for manufacturing the Al2O3-coated co-deposit whereby a substrate is immersed into a solution comprising at least one dissolved nickel salt, NiCrAlY or NiCoCrAlY particles, and Al particles in an electrochemical cell, DC current is pulsed into the electrochemical cell to electrodeposit Al, Ni, and NiCrAlY or NiCoCrAlY particles onto the substrate to form a deposited layer, and the substrate comprising the deposited layer is calcined to oxidize the Al particles and form the Al2O3-coated co-deposit.
