Different concentration of Al(No₃)₃ In Zro₂/Al₂o₃ double layer coating steel prepared by electrolytic method
(Trans Tech Publications, 2014)
Stainless steels, such as 440C steel are commonly used for engineering applications. The high carbon contents of this steel have significantly been attributed to low corrosion resistance properties. Surface modification ...
Effect of anodizing voltage on the morphology and growth kinetics of porous anodic alumina on Al-0.5 wt% Mn alloys
(Trans Tech Publications, 2014)
In this study, the effect of anodizing voltage on the morphology of porous anodic alumina and growth kinetics of anodizing of aluminium manganese alloy was reported. It was found that the increasing anodizing voltage affect ...
Surface morphology and corrosion behavior of electrolytic coatings in different aqueous solutions
(Trans Tech Publications, 2014)
ZrO₃/AI₂O₃, AI₂O₃/Y₂O₃, ZrO₂/Y₂O₃ coatings were applied on SS440C steel substrates via an electrolytic double layer coating process. The effect of these different ceramic aquecous solutions on the surface morphology and ...
Comparison study in consolidation of yttria reinforced iron-chromium composites using conventional and microwave sintering technique
(Trans Tech Publications, 2014)
This research is focused on studying the density and mechanical properties of iron-chromium composites consolidated by innovative rapid microwave sintering technology against conventionally sintered counterparts using slow ...
The effect of electrolyte temperature on formation of porous aluminium oxide films in anodising process
(AENSI Publisher All rights reserved, 2013-10)
A porous aluminium oxide film formed on aluminium was prepared in a mixed electrolyte of phosphoric acid and acetic acid solution. The morphology, growth and thickness of the film were investigated. The anodising process ...
Microstructural characterization of ZrO2 layer coating on martensitic stainless steel
(Trans Tech Publications, 2012)
High carbon steel stainless steel such as 440C martensitic stainless steel, are commonly used for automotive components, such as ball bearings, races, gage blocks and valve. In this study, 440C steel was coated with ZrO2 ...
Effect of manganese content on the fabrication of porous anodic alumina
(Hindawi Publishing Corporation, 2012)
The influence of manganese content on the formation of well-ordered porous anodic alumina was studied. Porous anodic alumina has been produced on aluminium substrate of different manganese content by single-step anodizing ...
Effect of sintering on the physical and mechanical properties of Co-Cr-Mo (F-75)/HAP composites
(Universiti Kebangsaan Malaysia, 2013-12)
This paper reports on the effects of HAP addition and sintering temperature on the microstructure and properties of the F-75/HAP composites fabricated by powder metallurgy. Co-Cr-Mo (F-75) is used in orthopedics because ...
Effect of electrolyte concentration on the growth of porous anodic aluminium oxide (AAO) on Al-Mn alloys
(Trans Tech Publications, Switzerland, 2012-12)
In this study, the effect concentration of electrolyte on pore nucleation process during anodizing was investigated. It was found that the concentration of oxalic acid influenced the morphologies and regularities of porous ...
Electrochemical characterisation of hybrid activators for aluminium sacrificial anodes in natural sea water
(Malaysian Citation Centre & Ministry of Education, 2013)
This paper reports on the electrochemical behaviour of as-cast Al-Zn-Mg alloys activated by tin (Sn) and ruthenium dioxide (RuO2) in natural sea water. The potential and advantages of Sn and RuO2 as hybrid activators in ...
