Previously, we studied the anodization of aluminum by adding alcohol to common acidic electrolytes with a focus on film formation efficiency and hardness anodic oxide film. In this study, difference in carbon number monohydric alcohols select propanol as an additive confirm whether effects behavior growth rate are universal regardless type. The tendency concentration dependence conductivity vis...

cross-wafer standard deviation of Jc was typically ~ 5% for anodized wafers but was ≥15% for unanodized wafers (Figure 6). A low variation in Jc results in a higher yield of device chips per wafer with the desired current density. As a result of the improved cross-wafer distribution, the cross-chip uniformity is greatly improved as well; typically < 1% for anodized chips. Low cross-chip Jc vari...

The aerospace industry mostly uses the aluminum alloys 2xxx and 7xxx series for their fuselage construction, some of them are assembled using structural bonding because it is strong, easy during fabrication process, resistant to corrosion, non-toxic. anodization process a proven surface treatment method bonding. Phosphoric Sulfuric Acid Anodizing (PSA) an eco-friendly alternative as chromate-fr...

introduction: the objective of this study was, wastewater quality investigation and removal efficiency of contaminants from the wastewater tile factory by using  coagulants includes ferric chloride, ferric sulfate and ferrous, aluminum sulfate and poly aluminum chloride in order to reuse it in the processing line. methods: this is an applied study. with regard to shiftwork schedules of the fact...

Anodic aluminum oxide (AAO) film with a thickness ranging from 20 to 100 μm was prepared using large-sized Al plate (4 cm × 10 cm) investigate the anodization parameter effect on and volume expansion factor. A corrosion treatment (voltage = 0 V) performed dissolution caused by acid. The actual anode surface temperature also measured confirm field-assisted nature of AAO dissolution. increases ex...

Anodic aluminium oxide (AAO) templates for multi-walled carbon nanotube (MWCNT) growth were produced by anodization of aluminium followed by pulse-reverse electrodeposition of cobalt inside the AAO pores. Cobalt functioned as the catalyst for H2/C2H2 chemical vapour deposition (CVD) growth of fairly well graphitized MWCNTs initiating inside the majority of the AAO pores and quickly growing beyo...
