Comparative study of corrosion behavior of AA2014/15 Vol%Al2O3p and AA2009/20 Vol% SiCw
Shamsul Baharin, Jamaludin; Z. Yusoff; Khairel Rafezi, Ahmad (Portuguese Electrochemical Society, 2008)The influence of heat treatment on the corrosion behavior of two aluminium matrix composites (AA2014/15 vol% Al2O3p - composite A and AA2009/20 vol% SiCw - composite B) was analyzed in 3.5% sodium chloride solution. The ... -
Effect of Inhibitors on the Corrosion of AISI-1018 Steel in Sea-Water Environment
Mohammed Misbahul, Amin; Khairel Rafezi, Ahmad (Research India Publications, 2008)The inhibitive properties of sodium benzoate for AISI-1018 steel controlling corrosion were studied in seawater environment at atmospheric condition. Three sets of solution were prepared with the concentrations of 0.3M, ... -
The influence of welding parameters and corrosive environment on the joint strength of resistance spot-welded mild steel sheets
Shamsul Baharin, Jamaludin; Ahmad Latiffi, A. A. T.; Khairel Rafezi, Ahmad; Fazlul, Bari (Universiti Malaya, 2009)In the present work, mild steel sheets consisting two batches were welded by resistance spot welding at different welding parameters and exposed under different environments. The 5% sodium chloride brine was used in the ... -
