In order to inhibit the breeding and propagation of bacteria and other source of infection, a novel method of fabricating an antibacterial metal matrix composite coating was reported. Graphene sheets decorated by silver-nanoparticles were doped in aluminum composite coating based on cold spray. The microstructure and antibacterial activity of the coating were investigated. Graphene sheets with silver-nanoparticles were scattered uniformly in the coating. Bacteriostatic experiment indicated the composite coating had high antibacterial activity. This metal matrix antibacterial coating avoids the drawbacks of organic coatings, promising to be used on facilities in hospital, home and laboratory. (C) 2019 Elsevier B.V. All rights reserved.
