| | 10~20μm thick copper and nickel finishings were coated on the sheet of expanded graphite by using electroplating method. Their tensile strength and weight loss on heating in air were measured, and compared with uncoated sheets. The technological factors that affect the coating quality are studied. The tensile strength of the sheet coated Cu and Ni is improved from 2.SMPa to 11MPa and 20MPa, the temperatures of resistance to oxidation are improved to 600℃ and 700℃.The results obtained... | | 用电化学方法在膨胀石墨板上镀覆了10~20μm厚的金属铜或镍层,测试了膨胀石墨板在镀覆金属前后的拉伸强度和动态热失重,并讨论了工艺因素对镀层质量的影响。膨胀石墨板镀Cu或Ni后,其拉伸强度可以从2.5MPa提高到11MPa或20MPa,抗氧化性温度从450℃提高到600℃或700℃。其镀层均匀,连续,与基体结合紧密。 | | 文摘来源 | | The temperature homogeneity effected by many elements has an important role in course of designs for a body of vacuum heat treatment furnace.These elements,which was dis- cussed exhaustively,contains a loss- on- heating sources,physical characteristic of materials,de- signs for a workpiece holder etc.For the temperature homogeneity to ensure in the vacuum fur- nace,at last,some measures were provided in this paper. | | 对影响真空热处理炉膛温度均匀性的各种因素进行了扼要的讨论与分析 ,并对保证炉膛温度均匀性的可行措施做了说明 ,所得结论得到了实践的证实。 | | 文摘来源 | | The magnetic compounds were prepared from Mg Al hydrotalcites by the method of co precipitation , and the magnetic Mg Al hydrotalcite particles sized in 20~50 nm were synthesized to give assembled layered magnetic materials. The influences of Mg/Fe(Ⅱ) molar ratio on the structure of hydrotalcites and its magnetic property were investigated by XRD, TEM, vibrating sample magnetometer(VSM), TG DTA and FT IR. The results showed that the addition of magnetic substrates didn't change the typical ch... | | 将磁性物种与镁铝水滑石进行复合 ,利用共沉淀法合成出粒径为 2 0~ 5 0 nm磁性纳米镁铝水滑石。样品的 XRD及热分析结果表明 ,镁铝水滑石掺入磁性物种后并没有改变其层状结构和 2个阶段质量损失的典型特征。样品的磁学性能测试结果表明 ,样品的比饱和磁化强度随磁性物种含量的增加而线性递增 ,这为层状材料与磁性物种进行复合制备新型功能材料提供了实验依据。 | | 文摘来源 | |   | | << 更多相关文摘 |
