介绍了一种新的成形加工工艺-等离子薄板柔性成形技术。它除了需要编制特殊的软件外,不需要特殊的设备和工具。初步的工艺性研究表明,成形弯曲角不仅与工艺参数,如电弧电流、电弧长度和运行速度有关,还与材料的物理特性,如热传导率、晶体结构及相变特性等有关。

【期刊论文】Microstructural characteristics in plasma sprayed functionally graded ZrO 2yNiCrAl coatings
潘春旭, Chunxu Pan a, , *, Xiaorong Xu b

Different functionally graded 20 wt.% MgO-ZrO2yNiCrAl thermal barrier coatings were obtained through the plasma spraying process. The microstructures, chemical compositions and fractured surface were examined by means of electron probe microscopic analysis (EPMA), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The SEM and EPMA results showed that: (1) microstructures and compositions varied gradually in the coatings; (2) the elements Cr and Al were enriched along the sprayed lamellae boundaries and leaded to the formation of oxides. TEM observation enabled finding the formation of dense dislocations and deformation twins, and also the formation of the oxides Al2O3 and Cr2O3 between grain boundaries. The SEM observations of the fractured surface revealed that the intermediate graded layer had the compositive mechanical properties in strength and toughness, due to the microstructure improvement and relaxation of residual stress concentration.

提出了一种利用脉冲电镀法在金属基板表面沉积一层具有催化活性的镍纳米晶,再将该基板放入乙醇火焰中合成碳纳米管(CNTs)和碳纳米纤维(CNFs)的方法。利用光学显微镜和X射线衍射仪(XRD)表征了镀层镍纳米晶的形貌和晶格特征,利用透射电镜(TEM)表征了碳纳米管的微观结构。实验研究了基板材料和电镀时间等因素对碳纳米管和碳纳米纤维合成的影响;初步讨论了其生长机理。
