In this study, a novel system for the detection and quantification of organofluorophosphonates (OFP) has been developed by using an optical sensing polymeric membrane to detect the fluoride ions produced upon OFP hydrolysis. Diisopropyl fluorophosphate (DFP), a structural analogue of type G chemical warfare agents such as Sarin (GB) and Soman (GD), is used as the surrogate target analyte. An op...
Aluminum alloy 7075 (Al 7075) has been widely used in aerospace and automotive industries to replace heavier alloys. This is because of its superior properties high specific strength, corrosion resistance, good formability, recyclability low fabrication cost. However, the ductility heat generation during drilling Al often produces a burr at entrance exit workpiece surface. research investigates...
In this paper, the tribocorrosion behavior and synergistic effect of 7075-T6 aluminum alloy under different applied loads (100, 150, 200 N) sliding velocities rpm) were studied in a 3.5 wt.% NaCl solution. Tribocorrosion experiments conducted tribobocorrosion system with pin-on-disc testing. The results show that interaction between load velocity significantly affects mechanical electrochemical...
هدف از این پژوهش توسعه ی مکانوشیمیایی نانوکامپوزیت های al6061/tib2 به منظور بهبود خواص مکانیکی و رفتار تریبولوژیکی آلیاژ al6061 است. در این راستا نانوکامپوزیت al6061-tib2 با روش آسیاب کاری مکانیکی و پرس گرم ساخته شد و رفتار مکانیکی و تریبولوژیکی آن بررسی شد. بدین منظور دو روش بصورت درجا و غیردرجا برای تولید پودر نانوکامپوزیت در نظر گرفته شد. جهت ساخت نانوکامپوزیت به روش غیردرجا ابتدا ذرات تقویت...
