Role of platinum in the Na2SO4-Induced hot corrosion resistance of aluminum duffusion coatings

Electrochemical corrosion measurements have been carried out with Pt-containing and Pt-free Al-diffusion coatings on IN 738 LC in a 90Na₂SO₄+ 10K₂SO₄ (mol%) melt at 1173 K. Pt improves the resistance to basic fluxing while there are no significant differences between both coating types in their resistance to acidic fluxing. The corrosion resistance of the Pt-containing coating is also higher in the passive potential region where protective scales rich in Al₂O₃ are formed. The reason for the different behavior of both coating types appears to be related to the high corrosion resistance of the Pt-rich surface layer of the coating and an increased Al₂O₃ content in the scale of the Pt-containing type.

全球铝轧制工业概览系列综述之九——日本神户钢铁公司真冈铝板带轧制厂

对日本神户钢铁公司枥木县真冈轧制厂的方方面面作了较全面的介绍，并对神户钢铁公司与美国铝业公司的合资企业－－神钢－美铝铝业有限公司作了附带的描述。这两家企业都是从上世纪70年代以来新建的高起点、高水平、高标准、高质量的世界级的铝板带轧制厂，前者的建设时间历20余年，是一步一步壮大的，原来（1＋3）式热连轧生产线，后改为（1＋4）式的，还有进一步改为（1＋5）式的余地。这是一个综合性强的铝板带加工厂，除生产罐料处，还可生产各种热处理可强化的硬合金板带材。该厂可作为中国今后建设全新的大型现代化铝板带轧制工程的模式。     

Assessing the effects of gamification in the classroom: A longitudinal study on intrinsic motivation,social comparison,satisfaction, effort,and academic performance

Gamification, the application of game elements to non-game settings, continues to grow in popularity as a method to increase student engagement in the classroom. We tested students across two courses, measuring their motivation, social comparison, effort, satisfaction, learner empowerment, and academic performance at four points during a 16-week semester. One course received a gamified curriculum, featuring a leaderboard and badges, whereas the other course received the same curriculum without the gamified elements. Our results found that students in the gamified course showed less motivation, satisfaction, and empowerment over time than those in the non-gamified class. The effect of course type on students' final exam scores was mediated by students' levels of intrinsic motivation, with students in the gamified course showing less motivation and lower final exam scores than the non-gamified class. This suggests that some care should be taken when applying certain gamification mechanics to educational settings.
