STUDY ON CORROSION PROPERTIES OF PLASMA NITRIDED PURE ALUMINIUM
Abstract: In this research plasma nitriding of pure aluminium and effect of iron elemental alloy on the formation and growth of aluminium nitride was investigated. Also corrosion properties of formed AlN were investigated. After preparation, the samples were plasma nitrided at 550oC, for 6, 9 and 12 h and a gas mixture of 25%H2-75%N2. The microstructure and phases analysis were investigated usi...
متن کاملAluminium dross-based insulating and exothermic materials for metallurgical industry
In the conducted investigations, aluminium dross, i.e. solid waste formed in the production and recycling of aluminium, was used as one of the basic raw materials to obtain a material characterised by insulating and exothermic properties, applied to heat riser heads in the process of iron or steel casting. The product was obtained by filtrating the slurry. In the raw mix, aluminium dross played...

The implementation of the achievements in material science both through history as well as today, is directly indicated in the improvement of the efficiency of transport means which then results in the improvement of the technology of traffic and transport. Today’s requirements in the area of engineering materials intended for the construction of transport means impose reduction of mass as one ...
متن کاملthe effect of esp materials on medical studentsreading proficiency
چکیده این تحقیق " مواد درسی " را به عنوان یکی از بحث برانگیزترین موضوعات آموزش زبان تلقی کرده و درتلاش است به سه سوال عمده پاسخ دهد: 1) آیا بکارگیری جزوات گرداوری شده توسط گروهی از مدرسین تاثیر بسزایی در میزان توانش خواندن و درک متون انگلیسی دانشجویان پزشکی دارد؟ 2) آیا استفاده از مواد درسی اصلی( بین المللی )، توانش خواندن و درک متون انگلیسی دانشجویان پزشکی را به طور چشمگیری تحت تاثیر قرار م...
15 صفحه اولRiveting Hammer Vibration and Nerve Damage
Hand Arm Vibration Syndrome (HAVS) is an occupational disease affecting 50% of riveting hammer operators after 10 years of work. Current international standards (ISO 5349) seeking to protect workers from occupational vibration are not effectively predicting HAVS onset. Scarce research has been done which investigates the long term effects of riveting hammer vibration exposure and nerve regenera...
