Effect of anodizing parameters on the growth of porous anodic aluminum oxide on al-mn alloys
Voon, Chun Hong; Mohd Nazree, Derman, Dr. (Universiti Malaysia Perlis (UniMAP), 2012-06-18)In this study, the effect of manganese content, anodizing voltage and concentration of electrolyte on pore nucleation process during anodizing was studied from current density versus time transient. It was found that the ... -
A simple one-step anodising method for the synthesis of ordered porous anodic alumina
Voon, Chun Hong; Mohd Nazree, Derman, Dr.; Uda, Hashim, Prof. Dr.; Khairel Rafezi Ahmad, Dr.; Ho, Li Ngee (Taylor & Francis, 2014)Porous anodic alumina (PAA) has been produced on aluminium substrate by single-step anodising at 50 V in 0.3 M oxalic acid at 15°C for 60 min. The highly ordered pore and cell structure was achieved by subjecting the PAA ... -
Synthesis of silicon carbide nanotubes from carbon nanotubes and silicon dioxide by microwaves irradiation
