1Effect of Temperature on Pitting Corrosion Resistance of 316 Stainless Steel Coated by Cerium Oxide Film in 3.5% NaCl Solution显示文摘One of the main problems of stainless steel is its poor pitting corrosion resistance in the aggressive environment containing Cl-,such as seawater.In this paper we investigated the corrosion behavior of the 316 stainless steel coated by cerium oxide nanocoating prepared by sol-gel process.Potentiodynamic polarization and electrochemical impedance spectroscopy(EIS)were used to study the corrosion behavior of cerium oxide nanocoatings in 3.5% NaCl solution.The microstructure of the cerium oxide was examined by scanning electron microscopy(SEM)and the formed phases was identified by X-ray diffraction(XRD).The pitting corrosion resistance of the cerium oxide nanocoating was found to be improved after heat treatment of the cerium oxide nanocoating at 300℃for 30 min.H.Hasannejad T.Shahrabi A.Sabour Rouhaghdam M.Aliofkhazraei 2008Journal of Materials Science & Technology2008,24,5:1
2Utilizing an auxiliary portable lube oil heating system in Aliabad Katoul-Iran V94.2 gas turbine during standstill mode:a case study显示文摘In a gas turbine power plant,the lubrication oil must be hot enough for the turbine start-up where the unit is in standstill mode.Currently,the strategy to heat the lubrication oil of ANSALDO V94.2 gas turbine power plant is operating the units in turning gear mode or interval mode.However,these strategies cause to suffering the power plant from high power consumption rate and aging.In this study,an auxiliary portable heating system was added to the unit 5 of the MAPNA built MGT-70(an Iranian version of V94.2)Aliabad Katoul-Iran power plant for increasing the lube oil temperature.Irreversibility,cost-effectiveness,and availability of the proposed heating system are studied by the concepts of exergy,economy,and reliability analyses,respectively.The result of the exergy analysis shows that by using the auxiliary portable lube oil heating system the exergy destruction decreases about 94.7%and 92.6%in comparison with turning gear mode and interval mode,respectively.The result of the economic analysis shows that the auxiliary portable heating system consumes less power rather than turning gear mode.Moreover,it is a cost-effective system which has no penalty and no non-profit production.Finally,the reliability analysis shows that the auxiliary portable lube oil heating system is a reliable tool during its lifetime.H.Hasannejad Seyyed Masoud Seyyedi M.Hashemi-Tilehnoee 2019Propulsion and Power Research2019,8,4:0
