增材制造

增材制造(包括3D打印)

增材制造(包括3D打印)已经成为一种非常有潜力的工程技术,它可以制造一些非标的工件,比如火箭发动机喷嘴、快速成型部件。可是,这种从下到上的制造过程给显微组织中缺陷(如杂质、孔洞和局部应力)的控制带来很大的挑战。

牛津仪器纳米分析提供针对生命科学应用进行优化的工具、相机和分析系统,可提高灵敏度,提高通量,并且改变了我们从生命的基本单位到复杂的医学研究来解释生物信息的方式。

粉末表征

许多增材制造工件尤其是金属构件的原料是粉末态,粉末的形态特征会影响到成品的质量。因此,需要控制粉末颗粒的形状(与流动性有关)、尺寸分布、成分及晶体结构,并减少外来杂质。在扫描电子显微镜(SEM)中快速、自动化地分析粉末质量是增材制造原材料品控中必不可少的步骤,它可以提供全面的粉末质量数据,为最终成品的质量质量控制提供支持。

    打印件的表征

    增材制造是一个快速进步的领域,不断涌现出新的制造方法和设备。因此,有必要使用有效的方法比较不同技术生产的成品件,理解打印工艺对产品性能的影响。

    对于增材制造的金属工件,EBSD是一种理想的分析设备。在扫描电子显微镜上配置EBSD,可充分发挥出高空间分辨率和高速分析的特点,提供全面的显微组织表征,包括晶粒、界面、相和织构等信息。
