The interaction of epoxy adhesives with steel surfaces

Deformable sandwich sheet materials have the advantage to be produced as raw materials and to be formed afterwards to even complex geometries. Moreover they are cost effective and predestinated for mass production. For such systems the necessity is given for a good bonding to guarantee a good shear transfer between the single layers. Because of deformation, failures by delamination often occur at the interface between the metal and the epoxy layer. Therefore investigations at this interface were performed using Atomic Force Microscopy (AFM) and X‐ray Photoelectron Spectroscopy (XPS), to understand the basic effect of the surfaces’ bonding behavior in selected preparation steps of the system. Basic information about the adhesion mechanisms between the stainless steel 316L and the epoxy is given. The chemical interaction between the epoxy and the steel results in a significant reduction of Fe³⁺ to Fe²⁺.

龙虎泡油田L126井区地质建模及优化水平井设计

龙虎泡油田L126井区为典型的低孔低渗油藏,经过多年开采综合含水率较高。通过对L126井区油藏三维地质建模及精细油藏描述,认为高Ⅲ3层孔隙度、渗透率、有效厚度、砂体连通性及剩余油含量均较高,适合作为水平井目的层。设计了L126-P14水平井,位于直井L124-14与L124-15之间,水平段长度440 m,水平位移787.74 m,地层倾角0.3°~0.5°,目的层标准层垂深1 699.0 m,完钻垂深1 849.6 m,钻遇层段2 067~2 503 m。油藏数值模拟结果表明,L126-P14水平井与周围直井相比产油量提升明显,验证了水平井设计的合理性。

Structure and properties of Ti(IV)-doped zinc hydroxychloride rusts formed at various temperatures

To simulate the atmospheric corrosion of steels galvanized with Ti–Zn alloys under different atmospheric temperatures, Ti(IV)-doped zinc hydroxychloride (Zn₅(OH)₈Cl₂·H₂O: ZHC) was prepared at various aging temperatures of 6–120 °C. Adding the Ti(IV) inhibited the crystallization and particle growth of ZHC, showing a minimum at 50 °C. Higher aging temperature promoted the formation of TiO₂ nano-particles. Elevating the aging temperature suppressed the adsorption of H₂O and CO₂ on Ti(IV)-doped ZHC. These results suggest that the alloying Ti in galvanized steel forms compact zinc rust layer at various atmospheric temperatures in marine environment, which would lead to the enhancement of corrosion resistance.     

Curvature Reversal and Residual Stress in Solid Oxide Fuel Cell Induced by Chemical Shrinkage and Expansion

Structural stability of layered functional ceramic composites is challenged by curvature effects and residual stresses caused by the thermal mismatch and chemical strains. In this study, a phenomenon of curvature reversal is found in the half‐cell structure of solid oxide fuel cell (SOFC) during the reduction of the half‐cell from NiO‐YSZ to Ni‐YSZ. An analytical model is derived to study the curvature and residual stress caused by the chemical shrinkage and expansion of anode. With reducing to Ni‐YSZ, the curvature of the half‐cell changes from the initial direction to an opposite direction, then back to the initial direction. This curvature reversal is inevitable during reduction while the thickness ratio of electrolyte to anode is between 0 and 0.102. The residual stress in electrolyte, calculated by the analytical model, is well agreement with the experiment result using X‐ray stress analysis. The YSZ layer is always subjected to compressive stress in despite of curvature reversal existing in half‐cell. It is impossible to get the residual stress by measuring the curvature unless the half‐cell was reduced completely.
