Summary: The long-term corrosion resistance of conventional micro-arc oxidation (MAO) coatings on magnesium alloy is limited by the inherent micro-scale pores. Zeolitic imidazolate framework-8 (ZIF-8) and zinc gluconate (ZnG) loaded ZIF-8 (ZnG@ZIF-8) were synthesized and incorporated into the MAO coating to enhance the corrosion resistance. The (ZIF-8 + ZnG@ZIF-8)/MAO composite coating showed significant improvement in corrosion protection compared to the blank MAO coating.

Summary: In this study, a series of MnCo2-xFexO(4) powders were synthesized by the sol-gel method to investigate the effect of partial Fe substitution on the physicochemical and electrochemical properties of MnCo2O4 spinel. The synthesized powders were characterized using various techniques. The findings revealed that the electrocatalytic activity towards oxygen evolution reaction (OER) was enhanced when Fe was partially substituted for Co, with the highest activity observed at x = 0.5. This indicates that tuning the eg occupancy at the octahedral sites through Fe substitution can modulate the catalytic activity of OER.

Summary: The microstructure and composition of the transition zone between the 16Mo3 steel boiler tube and 310 austenitic stainless steel weld overlay produced by the Cold Metal Transfer method were studied. The transition zone was found to have a complex structure related to the changing composition. Two distinct areas were observed in the transition zone, with the area near the fusion boundary exhibiting a two-phase structure. TEM investigation revealed the presence of a martensitic-austenitic structure in this area. The width of the martensite area in the transition zone of weld overlay can be significantly reduced by using a low-energy welding method.

Summary: This study investigates the creep behavior of two oxide dispersion strengthened alloys with Zr alloying addition through indentation creep tests at room temperature. The Fe-8Ni-xZr (x = 1 and 4 at.%, i.e., Zr-1 and Zr-4 alloys) alloys, fabricated by mechanical alloying and consolidation via equal channel angular extrusion, were used in the tests conducted under different loading rates. The results show that the Zr-4 alloy is harder but has lower creep resistance compared to the Zr-1 alloy. Both hardness and creep resistance are affected by the loading rate. Additionally, a possible creep mechanism is proposed. This study provides insights into the effect of microstructure on creep in oxide dispersion strengthened alloys at elevated temperatures.
