This paper presents the performance of metal oxide anode material, deployment and configuration of anode ground bed, and makes contrast of grounding resistance and protective potential between metal oxide anode and duriron anode 文章介紹了金屬氧化物陽極材料的性能、陽極地床的布置及結(jié)構(gòu),并對(duì)比了金屬氧化物陽極與高硅鑄鐵陽極的接地電阻和保護(hù)電位。
Microstructural change and thermal shock performance of metal / ceramic graded thermal barrier coatings in thermal shock experiments were studied by scanning electron microscope and energy-dispersive spectrometry . the results showed : 1 ) metal microstructure kept intact while ceramic microstructure had been destroyed; 2 ) thermal shock performance of coatings was interrelated with its function to relax residual stresses, therefore thermal shock performance of gradient thermal barrier coatings was better than that of terraced thermal barrier coatings; 3 ) thermal shock performance was concerned with metal content in metal / ceramic thermal barrier coatings, which would be improved when metal content was increased 利用掃描電子顯微鏡和能譜成分分析技術(shù)研究了金屬/陶瓷梯度熱障涂層在熱震過程中的顯微組織變化及其抗熱震性能.結(jié)果表明:1)金屬顯微組織保持完好,陶瓷顯微組織有明顯的破壞;2)涂層抗熱震性能與其熱應(yīng)力緩和功能密切相關(guān),梯度熱障涂層比階梯熱障涂層具有更高的抗熱震性能;3)金屬/陶瓷熱障涂層抗熱震性能與其中金屬相含量有關(guān),金屬相含量增加可改善涂層抗熱震性能
