The naturally formed oxide film on aluminum (Al) surfaces leads to low surface activity and poor interfacial adhesion, posing significant challenges for the construction of protective coatings via electrodeposition. In this study, we report a laser-enhanced electrodeposition (LED) strategy in a deep eutectic solvent composed of choline chloride and ethylene glycol to fabricate Ni/Ni–O composite coatings on Al substrates. Laser-induced localized heating activates the substrate, promotes the formation of finer nuclei, improves coating density, and accelerates cathodic ion reduction, resulting in compact coatings with strong interfacial adhesion. The prepared Ni/Ni–O coatings with a thickness of 28.6 μm exhibit high hardness of 73.8 HV, good anti-corrosion property (corrosion potential of 0.8 V and current density of 0.45 A/cm 2), and superior friction performance (coefficient of 0.20). Also, the coating performs excellent high-temperature anti-oxidation capacity, which demonstrates a minimal mass gain of only 0.13 mg/cm 2. The results demonstrate that the LED method provides a mechanically robust and scalable route for fabricating durable Ni/Ni–O coatings on Al alloys and holds promise for broader applications in functional surface engineering of lightweight metals
