propagation in an Al–Li alloy patch-reinforced structure. This paper proposes a method to determine the key parameters of the adhesive layer of adhesively bonded joints in the Al–Li alloy patch-reinforced... the adhesive layer breaks, and A is the cross-sectional area of the Al–Li alloy plate. The cohesive strength of the FM94 adhesive used in this paper, as given by Eq. (4), is 30.12 MPa. 2.4 Fracture energy......
Formation and capacitance properties of Ti-Al composite oxide film on aluminum YAO Lei(姚 雷), LIU Jian-hua(刘建华), YU Mei(于 美), LI Song-mei(李松梅), WU Hao(吴 昊) School of Materials Science... diffractometry (XRD) and electrochemical impedance spectroscopy (EIS). It was found that an anodic oxide film with a dual-layer structure formed between TiO2 coating and Al substrate. The film......

on molybdenum base TZM (Mo-0.5Ti-0.1Zr-0.02C) alloy[J]. Surface & Coatings Technology, 2012, 206: 3393-3398. [9] KRAKHMALEV P V, STROM E, LI C. Microstructure and properties stability of Al-alloyed...)2 materials. The Mo5(Si,Al)3 transition layer is found between the boundary of oxide scale and the Mo(Si,Al)2 substrate because of the diffusion of Si and Al elements. Key words: MoSi2; Al alloying......
depth profile analysis showed that the surface oxide film could be pided into three sub layers. The outside layer was mainly made up of magnesia, the middle layer, which consisted of beryllium oxide, magnesia and aluminum oxide, was compound and compact, the inside layer was a transition layer to substrate. Thermodynamic analysis indicated that the structure of the surface oxide film was accordant......
