A Brief Discussion about Nickel Aluminum Bronze Propeller Failure Modes and its Repair Methods

Nickel aluminum bronze is widely used in manufacturing propeller, in marine environment, propellers are easy to generate corrosion, it is important to find efficient solutions to repair corrosive propeller. In this study, it utilized OM and SEM to observe the failure modes of propeller, and discuss the feasibility of using cold spray (CS) technology to repair corrosive propeller. The study showed that failure modes of propeller includes corrosion, cavitations and abrasion, cold spray is possible an effective solution to solve these failures.
