Effect of Flame Hardening and Various Quenching Medium on the Mechanical and Metallurgical Properties of Grey Cast Iron Lathe Bed
Journal Title: International Journal of Advances in Scientific Research and Engineering - Year 2016, Vol 2, Issue 7
Abstract
Grey Cast iron is the most commonly used material in lathe bed. The properties of grey cast iron before and after the flame hardening process for different quenching medium is studied and analysed. The three quenching medium used are water, polymer and Sherol. The mechanical and micro structural behaviour of the material are determined and evaluated for the raw and treated specimens. The following properties are tested; hardness, wear and corrosion resistance. The hardness is tested using Rockwell hardness testing machine, the wear and corrosion resistance are tested using Pin on disc apparatus and Neutral salt spray test apparatus respectively. The micro structures are determined using metallurgical microscope.
