This paper aims at investigating the effect of graphene reinforced Al-Si coatings on corrosion behavior AA7075 aluminium alloy. Al - 12Si alloy powder with 0.5 and 1 wt.% was plasma sprayed substrate. Potentiodynamic polarization measurements were performed using CHI660E-CH electrochemical workstation. It observed that coating enhanced potential from –0.893 to –0.761 V reduced current density 1...

Thermal spray coatings are widely used in many applications, and the adhesion effect at coating/substrate interface plays an important role during service life. The thermal spraying coating substrate is primarily combined by a mechanical seizure effect. In this work, strategy to generate interfacial metallurgical bonding proposed. Plasma with wire feeding was adopted increase size of sprayed pa...
