A Effects of Nano-Particles Additives on Wear Performance of Micro-Arc Oxidation Coating Prepared on 2A12 Aluminum Alloy

Abstract:

Nano-particle reinforced composite coatings were prepared on 2A12 aluminum alloy by micro-arc oxidation and the effect of nano particles on wear performance of coating was studied. By means of SEM, CETR micro-nano-indenter friction and wear tester and white-light interferometer, the surface morphology and the friction and wear property were tested. Results showed that compared with the coating without nano-particle addition, the size and amount of pores on coatings were decreased substantially after additon with 20nm nano-SiO₂ particles, 80nm nano-SiO₂ particles and 80nm nano-TiO₂ particles, and the wear resistance of the micro-arc oxidation coating was improved.
