An approach based on film buckling under simple uniaxial tensile testing was utilized in this paper to quantitatively estimate the interfacial energy of the nanostructured multilayer films (NMFs) adherent to flexible substrates. The interfacial energies of polyimide-supported NMFs are determined to be ~5.0 J/m² for Cu/Cr, ~4.1 J/m² for Cu/Ta, ~2.8 J/m² for Cu/Mo, ~1.1 J/m² for Cu/Nb, and ~1.2 J/m² for Cu/Zr NMFs. Furthermore, a linear relationship between the adhesion energy and the interfacial shear strength is clearly demonstrated for the Cu-based NMFs, which is highly indicative of the applicability and reliability of the modified models.

The interface structure, work of adhesion, and bonding character of the polar TiC/Ti interface have been examined by the first-principles density functional plane-wave pseudopotential calculations. Both Ti- and C-terminated interfaces including six different interface structures were calculated, which present quite different features. For the Ti-terminated interface, the interfacial Ti-Ti bond has a strong metallic and weak covalent character; while for the C-terminated interface, the interfacial bond is a strong polar covalent interaction between the Ti-3d and C-2p orbital. The work of adhesion of C-terminated interface is nearly 9 J/m2 stronger than that of the Ti-terminated. It is found that each termination has relatively large work of adhesion, which is consistent with other polar interfaces.

为了提高镁合金的耐腐蚀性能,结合硅烷处理和胶粘涂层技术在AZ31镁合金表面制备了环氧防腐涂层.通过扫描电镜对涂层表面形貌进行观察,采用划格法、浸泡法及盐雾试验等分析镁合金表面硅烷处理对有机涂层的附着力及耐蚀性的影响.研究结果表明:采用KH-550型硅烷进行处理后,镁合金基体与有机涂层之间形成化学键,涂层与基体结合牢固,附着力为1级,耐饱和盐水23d不起泡.硅烷处理明显提高了有机涂层对基体的附着力和耐蚀性,因此,硅烷 + 胶粘涂层的方法可用于镁合金的表面防腐.

盘条氧化铁皮需要具有良好的附着性,以防止盘条表面出现锈蚀.盘条氧化铁皮也须具有良好的机械除鳞性能,防止盘条表面残余氧化铁皮过多,在拉拔过程带入钢丝表面,恶化钢丝表面质量.在工业生产过程中良好的氧化铁皮机械除鳞性能也容易使氧化铁皮附着性恶化,导致盘条表面过早裸露到空气中,出现锈蚀并产生废品.通过现场试验和理论分析研究了氧化铁皮附着性和氧化铁皮成分与厚度之间的关系.根据研究结果采取工艺改进措施,使盘条氧化铁皮附着性得到改善.
