Effect of Al2O3 on the Microhardness of AMg2/Graphite Nanocomposite Powder Gas Dynamic Coatings on Aluminum Alloys

  • Published:
Metal Science and Heat Treatment Aims and scope

Mechanically synthesized hybrid powders of the AMg2/graphite + Al2O3 system and coatings deposited by cold gas dynamic spraying from these powders are studied. The effect of Al2O3 concentration in the powder on surface morphology, structure and microhardness of the coatings formed is determined.
