The work aims to explore a microscopic observation system of paper surface and achieve high-precision stereoscopic observation with detail characterization of paper surface morphology. Based on the DT-400E precision program-controlled three-dimensional translation stage and KEYENCE LJV-7200 two-dimensional laser scanner, the hardware parts of our own system are developed to scan and transmit point cloud data of paper surface morphology to the computer. The corresponding system software will automatically process the point cloud data acquired from the laser scanner and generate the corresponding vivid 3D model and height histogram. This system scans and characterizes four different types of paper samples, allowing the human eye to visually distinguish the differences in surface morphology as well as automatically calculate the numerical differences in paper surface morphology parameters. The results of the applicability test show that the system is highly efficient in acquiring, observing, and evaluating the topography of the paper surface. The system can not only predict the paper surface quality of printed paper, but can also be extended to the evaluation of 3D printed surfaces.

Al/B composite is a new structural-functional integration material, which has a promising potential in future application due to their good combination of neutron shielding property and mechanical property. In order to obtain sintering process parameters of Al/B composite, the mold pressure, sintering temperature and the composition of powders were investigated and the physical properties of Al/B composite also systematically studied. In addition, the surface morphology of Al/B composite was analyzed. The experimental results indicate that the relative density will be higher when the mold pressure was bigger in appropriate pressure intervals, and when the mold pressure was more than 144MPa, the composites was difficult for molding because of the great internal stress. From the analysis of morphology, it shows that the best sinter temperature interval is 550-580°C. From the studies of composition of powders, it has been found that the percentage of Al affect the density and hardness. The density will be higher if the percentage of Al is higher.

The interest in producing cost-effective 3D printed metallic materials is increasing day by day. One of these methods, which has gained much attention recently, is the fused deposition modelling (FDM) method. The parameters used in the FDM method have significant effects on the printed part properties. In this study, CuSn10 bronze alloy was successfully produced. The printing speed and layer thickness were investigated as the printing process parameters, and their effect on morphological properties was characterized by using SEM. As a result, it was observed that the formation of printing-induced voids was prevented by applying a layer thickness of 0.2 mm. Additionally, by increasing printing speed, a slight decrease in product density was observed. Following determination of 3D printing parameters which give the highest printed part density, the parts were debound in hexane solution via solvent debinding. Finally, the parts were sintered at 850, 875 and 900 °C for 5 h to examine effect of sintering temperature on density, porosity, shape deformation and mechanical properties. Although partial slumping started to form over 875 °C, the highest density (94.19% of theoretical density) and strength (212 ± 17.72 MPa) were obtained by using 900 °C as the sintering temperature.

This research is aimed to study the effect of sintering temperature on crystalline structure and surface morphology of NdFeO3 oxide alloy materials. NdFeO3 was synthesized by solid state reaction method with mixing of 99.9% Nd2O3 and 99.9% Fe2O3 as precursors. Three samples with different process were made in this experiment. The 1st (#1) and 2nd (#2) samples were sintered for 84 hours at 950°C and 600°C. Calcination procces was carried out at 950°C for 50 hours. The 3rd (#3) sample was sintered for 84 hours at 600°C without calcination process. The samples were characterized by using SEM (Scanning Electron Microscopy) and XRD (X-Ray Diffraction). Based on the SEM characterization result, it was obtained that the sintering temperature influence on surface morphology of NdFeO3 grain size. The XRD analyze was obtained FWHM (Full Width at Half Maximum) value of sample #1, #2 and #3 are 0.11°, 0.10°, and 0.31°, respectively. The value of FWHM was associated with the peak at 2Θ of 32.53° for all sample, it is indicated of hkl (121). Further calculation based on crystallography data was carried out by rietveld method with rietica software and the best quality will be applied as a gas sensor materials.
