materials to help choose the right kind of materials for a specific application. After material is chosen‚ one way to improve upon its properties is to apply heat treatment processes. A heat treatment involves rapid heating or cooling of a metal or alloy at extreme temperatures. For decades‚ engineers obtain desirable strength and hardness by austenitizing the steel and then quenching it to form martensitic structure. After fully converting to martensitic‚ steels are tempered to achieve right amount

bioactive ceramic coating hydroxyapatite (HAP). The stress concentrations for the coated hip implant showed 20 -30 % reduction in 316L Stainless steel (SS)‚ 30 % in Titanium alloy and 20 % in cobalt chromium alloy. Among them‚ Co-Cr alloy gives better reduction in stress distribution and deformation compared to Titanium alloy and 316L Stainless steel (SS). In conclusion‚ a bioactive coating has tremendous potential for improving bone integration of a wide range of dental and orthopaedic

Bell then evolved this rudimentary procedure into a more controlled alloy in 1819. The substance created a massive wealth for the dental surgeons who promoted its use. However‚ the substance was actually overused‚ and in 1845 a convention of dental surgeons agreed to stop its use altogether. They believe that the substance
