Bronze Casting

Nickel aluminum bronze (NAB) castings possess favourable combinations of strength and resistance to corrosion, biofouling and cavitation/erosion, and so have long been used in naval applications. Nonetheless, in seawater environments NAB castings are susceptible to selective phase corrosion and so such components periodically require either replacement, which is very costly, or repair. However, repairs involving traditional, high heat input welding operations can lead to distortion and microstructural changes that unacceptably degrade NAB corrosion performance, and so repairs are not commonly performed. In the present work, cold spray is explored as an alternative for NAB (alloy CuAl9Fe5Ni5) repair without excessive distortion or base metal degradation, and preliminary results of its performance reported. Suitable cold spray parameters have been determined using an iterative approach by analyzing deposits in terms of microstructure, porosity and adhesion to the substrate. It is intended that these parameters will later be used to create simulated repairs which can be more thoroughly characterized for strength, toughness and corrosion performance.

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.

The effect of oxide film on the cavitation erosion-corrosion of nickel-aluminum bronze (NAB) alloy in 3.5 wt% NaCl solution was investigated via pulse and continuous cavitation modes of ultrasonic vibrator device according to ASTM. NaCl solution was used to simulate the seawater condition of NAB alloy. In the same effective cavitation erosion time of 8 h, the total mass loss caused by continuous cavitation erosion-corrosion was 21.45±0.75 mg, which was almost 1.5 times as much as that of pulse mode. The synergistic effect of cavitation erosion and corrosion was analyzed. The results showed that the total contribution of the synergy component in the process of continuous cavitation erosion-corrosion was 51.66%, while it fell to 25.56% in the pulse mode. The open-circuit potential measurements and electrochemical atomic force microscope test demonstrated that the rapid repair of an oxide film during pulse cavitation played an important role in resisting the cavitation erosion-corrosion. Furthermore, the formation process of oxide film was in situ observed, indicating higher nucleation rate compared with its growth rate. Also, the alloy with such film exhibited lower synergy in pulse mode than that without film in continuous mode.
