目的 研究枪械自动机关键材料在海洋腐蚀环境下的腐蚀行为及其对自动机构件性能影响。方法 采用实验室全浸腐蚀试验,结合腐蚀质量损失分析、电化学测试、摩擦系数测试及扫描电镜观测,分析样品的腐蚀质量损失、表面形貌演变、电化学参数及摩擦系数的变化规律。结果 随试验时间延长,材料腐蚀质量损失速率加快,表面形貌由初期点蚀和裂纹逐渐发展为大面积剥落。腐蚀电位负移,腐蚀电流密度增大,基体加速溶解,耐蚀性能下降。摩擦系数升高,运动阻力增大。结论 腐蚀导致表面逐渐粗糙,自动机构件动作阻力增加,功能逐步丧失。
Abstract
The work aims to investigate the corrosion behavior of key firearm automatic mechanism materials in marine corrosive environment and its impact on automatic component performance. Laboratory immersion corrosion tests were conducted and combined with corrosion weight loss analysis, electrochemical measurements, friction coefficient tests, and scanning electron microscopy observations, the corrosion weight loss, surface morphology evolution, electrochemical parameters, and friction coefficient variations of the samples were analyzed. With prolonged testing, the corrosion weight loss rate of the materials accelerated, and the surface morphology progressed from initial pitting and cracks to extensive peeling. The corrosion potential shifted negatively, the corrosion current density increased, and the substrate dissolution accelerated, indicating a decline in corrosion resistance. The friction coefficient increased, resulting in greater motion resistance. The results show that corrosion causes the surface to become increasingly rough, increases the resistance of the automatic mechanism components, and gradually leads to the loss of functionality.
