in this study, mixed metal oxides al2o3/mgo/tio2 coatings with al/mg/ti ratio of 5:1:3 and 2.5:3:4 were coated on aluminum by sol-gel method. the surface morphology, phase analysis, thermal behavior and the corrosion behavior of the al2o3/mgo/tio2 coatings were characterized by (sem), (xrd), (tg-dta) and potentiodynamic polarization test in 3.5 wt.% nacl solution. the results demonstrated that ...

Corrosion of Aluminum metal at pH 10 has been controlled by dicarboxylic acids such as oxalic acid (OA) and adipic (AA).The Inhibition efficiency (IE) determined the classical weight loss method. The maximum inhibition offered (AA) 250 ppm Zn2+ 50 system are 88 96%. To determine values Linear Polarization Resistance (LPR) corrosion Current (Icorr), potentiodynamic polarization study used.

This study investigated the effects of deposition techniques on the microstructural and tribological properties of Ti/TiN/TiCN/TiAlN multilayer coatings onto a Custom 450 steel substrate. The coatings were produced using cathodic arc physical vapor deposition (CAPVD) and plasma-assisted chemical vapor deposition (PACVD). The microstructural of the coatings was evaluated using (SEM), and phase f...
