首先对不同粘结剂和浓度的粗粉坯体上下表面进行机械研磨,使其上下表面平行且平整,通过配有能谱仪EDS的ZEISS Sigma 300扫描电子显微镜观察粘结剂和粗粉的粘结机制。
Firstly, the upper and lower surfaces of the coarse powder green bodies with different binders and concentrations were mechanically ground to make them parallel and flat. The bonding mechanism between the binder and the coarse powder was observed through a ZEISS Sigma 300 scanning electron microscope equipped with an energy dispersive spectrometer (EDS).
