Taking the rare earth magnesium alloy as the research object, an organic-inorganic composite passivation film is prepared by using silane-modified trivalent chromium passivation solution. To investigate the effects of process parameters such as silane concentration and passivation time on the quality and performance of the film, micro-morphology, film thickness, adhesion strength, and neutral salt spray tests are conducted. To investigate the influences of process parameters such as silane concentration and passivation time on the quality and performance of the film, microscopic morphology, film thickness, adhesion force and neutral salt spray test are conducted. The results show that the synergistic mechanism between silane and trivalent chromium could effectively fill the defects of the film, improve the compactness, and thereby enhance the corrosion resistance. The silane concentration is a key factor influencing the density of the film. When the silane concentration is too low, the three-dimensional network structure formed through cross-linking could not fully fill the pores of the passivation film, resulting in limited protective effect; while a reasonable silane concentration is conducive to the formation of a dense and uniform passivation film, effectively blocking the corrosive medium. Compared with not adding silane, the annual corrosion rate of the sample decreases by 65.97% (0.211 mm/a), but the duration of the passivation treatment needs to be controlled to avoid the slight dissolution of the passivation film in the trivalent chromium passivation solution, which would subsequently reduce the protective performance.

以稀土镁合金为研究对象，采用硅烷改性三价铬钝化液，制备有机-无机复合钝化膜，为研究硅烷浓度、钝化时间等工艺参数对膜层质量及性能的影响，进行微观形貌、膜层厚度、结合力及中性盐雾试验。结果表明：硅烷与三价铬的协同机制可有效填补膜层缺陷、改善致密性，从而提升耐腐蚀性能。硅烷浓度是影响膜层致密性的关键因素，当硅烷浓度过低时，交联形成的三维网络结构无法充分填补钝化膜孔隙，防护效果有限；而合理的硅烷浓度有利于形成致密均匀的钝化膜，有效阻挡腐蚀介质，相比不添加硅烷的样品，样品的年腐蚀速率下降了65.97%（0.211 mm/a），但需控制钝化处理时长，避免试样在三价铬钝化液中长时间浸泡导致钝化膜轻微溶解，进而降低防护性能。
