Aluminium types 7075,2024 and magnesium casting alloys are widely used in aircarft components, example Helicopter because of their inherent weight advantages over other metals but premature failure due to corrosion is one of the main challenges associated with this alloys, which affects the safety and readiness of aircraft. This paper is an outcome of project to address corrosion problem at Helicopter part using supersonic particle deposition as potential corrosion treatment method in Malaysia.Current practise of corrosion treatment by OEMs such as Sikorsky are using DOW-17 process or thermal spray coating. Disadvantage of DOW-17 process,it involve hazard material and Thermal spray coating issue of porosity and fatigue failure.The procedure focusing on particle deposition at supersonic level using material powder that suitable with substrate.Supersonic particle deposition using Aluminium coating will provide total solution for corrosion treatment for Aluminum airframe structure.There is no application yet of this coating technology in Malaysia and on top of that, coating at low temperatue that creates negligible heat affected zone and lead to excellent fatigue properties between deposited material and substrate, this will contribute to a big potential of SPD application in aircraft, automotive and tooling industry .
