Preparation and characterization of the electrodeposited Cr-Al2O3/SiC composite coating

► SiC content reaches up to 2.5 wt% in codeposition of Cr-Al2O3/SiC composite coating. ► Al2O3 coated SiC as dispersed particles in Cr plating bath. ► Modification increases zeta potential and favors the deposition of SiC particles. ► Combination of coelectrodeposition and modification of nano ceramic particles.
