Different concentration of Al(No₃)₃ In Zro₂/Al₂o₃ double layer coating steel prepared by electrolytic method
Siti Hawa, Mohamed Salleh; Mohd Nazree, Derman, Dr.; Mohd Zaidi, Omar; Rohaya, Abdul Malek (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 deposition time on properties of ZrO2 coating prepared using electrolytic method
Siti Hawa, Mohamed Salleh; Terng, Lim Wuh; Mohd Nazree, Derman, Dr.; Mohd Zaidi, Omar; Salmie Suhana, Che Abdullah (Trans Tech Publications, 2013)AISI 440C martensitic stainless steel is one of the most widely studied engineering materials for its tribological properties. It is capable of attaining the best mechanical properties such as high strength and hardness ... -
Microstructural characterization of ZrO2 layer coating on martensitic stainless steel
Siti Hawa, Mohd Salleh; Mohd. Zaidi, Omar, Prof. Madya Dr.; Mohd Nazree, Derman, Dr.; Salmie Suhana, Che Abdullah (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 ... -
Surface morphology and corrosion behavior of electrolytic coatings in different aqueous solutions
Siti Hawa, Mohamed Salleh; Mohd Nazree, Derman, Dr.; Mohd Zaidi, Omar; Rohaya, Abdul Malek (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 ...
