Copper alloys have widely used for marine plants, ship building equipment, and renewable energy facilities under marine environment due to its excellent castability, durability, and corrosion resistance. In this study, the surface of ALBC3 alloy was modified with shot peening time to improve the strength and cavitation characteristics. For evaluation of cavitation resistance, cavitation experiments for the non-shot peened and shot-peened specimens were performed to investigate the extent of damage and determine the weight loss. As a result, the shot peened ALBC3 alloys improved cavitation resistance. In particular, the shot peening time of 3.5 min was considered to be the optimum shot peening condition since it presented an improvement of 35.7% in cavitation resistance.
铜合金由于其优异的铸造性、耐久性和耐腐蚀性，广泛应用于海洋环境中的海洋植物、船舶制造设备和可再生能源设施。在这项研究中，通过喷射时间对 ALBC3 合金的表面进行了改性，以提高其强度和空蚀特性。为了评估抗空蚀性，对未经喷射处理和经喷射处理的试样进行了空蚀实验，以研究损伤程度并确定重量损失。结果表明，喷射处理的 ALBC3 合金提高了抗空蚀性。特别是，喷射时间为 3.5 分钟的处理条件被认为是最佳的喷射处理条件，因为它使抗空蚀性提高了 35.7%。
