    摘要:

    研究交替盐雾环境下Ti-15-3钛合金与MT700/603B碳纤维复合材料的接触腐蚀行为,分析碳纤维表面状态、缝隙宽度、腐蚀时间等对腐蚀敏感性和腐蚀特征影响。结果表明,缝隙宽度为0.06 mm时钛合金腐蚀最为严重。缝隙腐蚀和接触腐蚀相比,在相同腐蚀条件下后者的腐蚀失重速率、腐蚀氧化层面积均显著大于前者,表明钛合金接触腐蚀的腐蚀程度较缝隙腐蚀更为严重。Cr分布不均匀区域腐蚀更为严重。

    Abstract:

    The galvanic corrosion behavior of Ti-15-3 titanium alloys and MT700/603B carbon fiber reinforced resin composites in alternate salt spray environment was studied. The effects of carbon fiber surface state, gap width and corrosion time on corrosion sensitivity and corrosion characteristics were analyzed. The results show that titanium alloy suffers the most serious degradation when the gap width is 0.06 mm. Compared with crevice corrosion, the corrosion weight loss rate and corrosion oxide area of galvanic corrosion are significantly larger under the same corrosion conditions, which indicates that the corrosion degree of galvanic corrosion is more destructive than crevice corrosion. The corrosion damage is more drastic in Cr region with nonuniform distribution.
