研究激光粉末床熔融增材制造(AM)(又称直接金属激光烧结)技术制备的Ti6Al4V合金等离子体电解氧化(PEO)处理及其电化学行为。通过短时间(<120 s)PEO处理(也称闪速PEO),在AM合金和传统合金表面制备了3~10μm厚、含Ca和P的涂层。然后在改良的α-MEM溶液中,通过动电位极化曲线和电化学阻抗谱(EIS)评估了合金的电化学行为。与传统合金相比,AM合金中形成了细小的层片状α显微组织和层间小尺寸的β相颗粒,这促使了火花的产生,从而促进了PEO涂层的生长。闪速PEO涂层提高了传统合金和AM合金的耐腐蚀性,最薄的涂层(<3μm)提供了高达3倍的保护。AM Ti6Al4V由于其高的晶界密度,易受局部缝隙腐蚀的影响。而即使短至35 s的闪速PEO处理也足以成功避免这种情况。

The development, production and utilization of renewable energy, energy storage and green hydrogen and the associated technologies in Sri Lanka have great potential to contribute to the United Nations' Sustainable Development Goals (SDGs). The island aims to achieve 70% electricity generation from renewable energy sources by 2030 (within the target of 40% utilization of renewable energy sources for the entire energy generation of the country by 2030). The power sector has to invest US$11 billion from 2023 to 2030 to contribute to reaching this target. This commentary aims to provide a critical perspective on the recommendations of the report from the National Science and Technology Commission's 9th biennial conference in 2023 on science and technology, the sub-thematic technical report on clean energy, energy storage and green hydrogen in line with the SDGs in the Sri Lankan context. The technical report provides insightful recommendations for Sri Lanka's energy sector under three main sections: renewable energy, energy storage and green hydrogen. Also, it explores the potential of various renewable energy sources, energy storage systems and green hydrogen as sustainable solutions to address the country's energy challenges while emphasizing the spillover effects of them, which could contribute to the enterprise's job creation and uplift the economy. This commentary provides a critical perspective on clean energy, energy storage and green hydrogen in line with the United Nations SDGs in the Sri Lankan context based on a recent report from the National Science and Technology Commission of Sri Lanka.

The technology, structures and magnetic properties of Nd4.5Fe76Co1b18.5 nanocomposite magnets were investigated. The effect of crystallizing treatment temperature and time on structures and magnetic properties of Nd4.5Fe76Co1b18.5 amorphous ribbons was studied. The results show that Nd4.5Fe76Co1b18.5 containing more analogue metals is easy to form amorphous. The magnetic properties of 16 m/s quenched ribbon for 710°C × 900 s crystallizing treatment are as follows: iHc=242.1 kA/m, br=0.9410 T and (bH)max=59.64 kJ/m3. The even grain size is as follows: D(Fe3b)=34 nm and D (Nd2Fe14b)=23 nm.
