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...

An attempt has been made to investigate the machinability of zirconia toughened alumina (ZTA) inserts while turning AISI 4340 steel. The insert was prepared by powder metallurgy process route and the machining experiments were performed based on Response Surface Methodology (RSM) design called Central Composite Design (CCD). The mathematical model of flank wear, cutting force and surface roughn...
