1烯烃厂的结焦控制——降低炉管结焦:表面涂层材料和冶金技术的完美结合显示文摘乙烯裂解炉中,结焦的形成会减少产品收率,增加能耗并缩短炉管设计寿命.乙烯生产人员通常要为因产品收率下降而平衡运行周期,并在此方面作出努力.延长两次清焦操作之间的有效生产时间已成为烯烃生产企业所追求的目标.A.G..Wyslerski G.Fisher C.M.Schillmoller 2001乙烯工业2001,13,3:5
2Systematic review: the efficacy of treatments for irritable bowel syndrome – a European perspective显示文摘J.TACK M.FRIED L. A.HOUGHTON J.SPICAK G.FISHER 2006Alimentary Pharmacology & Therapeutics2006,,2:1
3磨损条件对碳化钨基复合涂层性能的影响显示文摘通常,在油砂开采过程中,标准合金不具备在磨损和腐蚀条件下抗磨损性能。对于生产性关键组件,通常采用碳化钨基复合涂层(MMC)来延长设备寿命,防止非计划性停运。复合涂层的性能主要依赖磨损环境。本文将对碳化钨基复合涂层在不同的研磨条件下的机械性能和结构性能进行研究,探讨这种交互作用如何在决定性能等级上起到关键作用。这些信息会为更好的选材提供依据,甚至可延长零部件的寿命。g.fisher t.wolfe 杨晓剑(译) 2016热喷涂技术2016,8,4:1

5碳化物特性对HVOF喷涂碳化钨基涂层结构和性能的影响显示文摘油砂和重油矿床的开发环境对装备性能具有很高的挑战性,研磨砂和腐蚀介质结合可以使元器件的寿命缩短和失效。延长仪器使用寿命的常用方法是应用HVOF-喷涂碳化钨基涂层,基于此,大量的商用纳米结构涂层已经被开发并获得应用。本文以纳米结构碳化钨基粉末为原料,采用HVOF法制备了涂层,重点研究该涂层的力学和耐磨性能。G.Fisher T.Wolfe 李会谦 2013热喷涂技术2013,,2:1

7Growth of single crystals in the (Na_(1/2)Bi_(1/2))TiO_(3)-(Sr_(1-x)Ca_(x))TiO_(3) system by solid state crystal growth显示文摘Ceramics based on(Na_(1/2)B_(1/2))TiO_(3) are promising candidates for actuator applications because of large strains generated by an electric field-induced phase transition.For example,the(1-x)(Na_(1/2)Bi_(1/2))TiO_(3)-xSrTiO_(3) system exhibits a morphotropic phase boundary at x=0.2-0.3,leading to high values of inverse piezoelectric constant d_(33),which can be further improved by the use of single crystals.In our previous work,single crystals of (Na_(1/2)B_(1/2))TiO_(3)-SrTiO_(3) and (Na_(1/2)Bi_(1/2))TiO_(3)-TiO_(3) were grown by the solid state crystal growth technique.Growth in the(Nai/2Bi/2)TiO3-SrTiO3 system was sluggish whereas the (Na_(1/2)B_(1/2))TiO_(3)-CaTiO_(3) single crystals grew well.In the present work,0.8(Na_(1/2)Bi_(1/2))Ti0_(3)-0.2(Sr_(1-x)Ca_(x))Ti0_(3) single crystals(with x=0.0,0.1,0.2,0.3,0.4)were produced by the solid state crystal growth technique in an attempt to improve crystal growth rate.The dependence of mean matrix grain size,single crystal growth distance,and electrical properties on the Ca concentration was investigated in detail.These investigations indicated that at x=0.3 the matrix grain growth was suppressed and the driving force for single crystal growth was enhanced.Replacing Sr with Ca increased the shoulder temperature T_(s) and temperature of maximum relative permittivity T_(max),causing a decrease in inverse piezoelectric properties and a change from normal to incipient ferroelectric behavior.Phan Gia LE Huyen Tran TRAN Jong-Sook LEE John G.FISHER Hwang-Pill KIM Wook JO Won-Jin MOONC 2021Journal of Advanced Ceramics2021,10,5:0
