Several 2-thiohyd?nt?in?Shiff base derivatives were prepared as ecofriendly corrosion inhibitors for mild steel in acid environment. Their anticorrosion properties studied on 0.5 M HCl solution electrolyte by using usu?l gr?vim?tri? and different el??tr??hemic?l techniques (w?ight l?ss m??sur?m?nt, p?t?nti?dyn?mi? p?l?riz?ti?n p?t?nti?st?ti? ?l??tr??h?mic?l imp?d?n?? s???tr?sc???).

Abstract The cause of a rare cracking failure accident the polyethylene (PE) anti-corrosion layers pipeline is analyzed and determined. properties PE raw materials were detected according to standard, micro-morphology was characterized by scanning electron microscope (SEM). storage modulus loss at range -100~40 °C tested dynamic mechanical analysis (DMA), stress low temperature (-40 °C) calcula...
