Fabrication of nanodiamond reinforced aluminum composite coatings by flame spraying for marine applications

In this study, nanodiamond (ND) reinforced Al metal matrix composite coatings with enhanced mechanical properties were fabricated by flame spraying the mixture of micron-sized Al powder and ND suspension for the first time. Microstructural characterization and assessment of mechanical/corrosion properties of the Al-ND composite coatings were conducted. Results show that the coatings with perfectly retained ND exhibit reduced porosity and increased hardness, exhibiting remarkably enhanced anti-corrosion and anti-wear performances. The study presents a promising way to develop ND reinforced metal matrix composite coatings for potential marine applications.Graphical abstract
