摘　　要：对煤矿井下液压支架结构件用金属材料制成的挂片开展模拟浸泡试验、干湿交替试验,并对试验后的挂片进行腐蚀速率分析,针对腐蚀产物进行宏观形貌分析、扫描电镜(SEM)分析、X射线衍射谱图(XRD)分析,进一步研究煤矿井下液压支架结构件的腐蚀机理,为结构件腐蚀失效分析、腐蚀控制提供理论依据。The simulated immersion test and alternative dry and wet test are carried out for samples made of metal materials for hydraulic support structures in underground coal mines. Then the corrosion rate analysis is carried out, meanwhile, the corrosion products are analyzed via macroscopic morphology analysis, scanning electron microscopy and X-ray diffraction spectrum. The corrosion mechanism of underground hydraulic support structures in coal mines is further discussed,which can provide theoretical basis for the failure analysis and corrosion control of the structures.
