Microstructure, hardness and wear resistance of AZ91 magnesium alloy produced by friction stir processing with air cooling

Abstract: Friction stir processing (FSP) was used to modify the surface layer of the AZ91 magnesium alloy. The treatment was carried out using a jet cooling nozzle, generating a stream of cold air and enabling intensive cooling of the friction stir processed (FSPed) zone. Single-pass FSP was carried out using a tool rotational speed of 500 rpm and travel speed of 30 mm/min. The treatment was conducted using a truncated cone-shaped tool with a threaded side surface. Strong grain refinement and microstructural changes typ… Show more

“…Its potential applications could be related to aerospace and automotive industry [3][4][5], electronic systems and even in medicine [6,7]. Nevertheless, there are significant disadvantages of magnesium alloys, mostly connected with their Investigations on the Microstructure and Corrosion Performance of Different WC-based Cermet Coatings Deposited by High Velocity Oxy Fuel Process onto Magnesium Alloy Substrate poor mechanical properties, wear and erosion resistance [8,9]. However, the crucial drawback that prevents their widespread application is an impoverished corrosion performance [10,11].…”
