circumstances than anchor bolt corrosion and failure. For example, PENA et al [31] built hydrogeochemical models to study the corrosion rate of carbon steel canisters used for the geological disposal of high-level radioactive waste. KLAPPER et al [30] focused on modelling the corrosion rate of scaling and corrosion influencing technical facilities during geothermal energy production. Considering......

AA2024 (Al-Cu-Mg) aluminium alloy is commonly used after precipitation hardening at 190 °C (artificially aged alloy). This alloy is also commercially used after natural aging......
数,如炸药的种类,材料的物化性质等等;动态参数是指爆炸过程中系统处于动态变化的参数,如碰撞点速度,碰撞角γ,偏转角β,炸药爆速等[13].图1所示为爆炸焊接法制备钛/铝复合板的示意图[14]. 图1 爆炸焊接法制备钛/铝复合板示意图[14] Fig. 1 Preparation diagram of Ti/Al explosion composite plate[14...对结合强度的影响可以成为提高复合板综合性能的新思路. 图2 Ti/Al/Ti爆炸复合板结合界面[14] Fig. 2 Bonding interface of Ti/Al/Ti laminate composites[14] 1.2 轧制复合法 轧制复合法是指将异种金属板叠层组坯后送入轧机辊缝进行轧制,依靠轧机的强大压力使金属板材发生塑性变形,待复合金属表层发......
environment, a passivation film of Ta2O5 is formed on the alloy surface, which is more stable than ZrO2 and TiO2 [14]. In addition, BALLA et al [15] found that Ta, having improved biocompatibility..., a coating layer of cubic boron nitride was applied on the inner surface of the graphite sheet as a thermal barrier layer, which inhibited the diffusion of carbon during sintering. The SPS sintering......
treatment. More importantly, it was reported in 2008 that the structure remained in a fully passive condition after the treatment [5]. To facilitate the implementation of ECE technology, UEDA et al [6] fastened an anode system onto the surface of concrete using ductile fiber-reinforced cementitious composites. Similarly, ZHU et al [7] adopted a carbon-fiber-reinforced polymer as an external anode. JIN......
