Abstract: Electron trapping materials SrSO₄:Eu²⁺ were prepared by hydrothermal method from fatty alcohol polyoxyethylene (3) ether (AEO-3) aqueous solution at 200 °C for 20 h. The phase structure, microstructure and optical properties were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM) and excitation-emission spectroscopy (PL-PLE), respectively.

Abstract: The green design of ceramic products in the era of information should pay attention to quality, lifetime and function of products, and should consider green design of product function, structure and material, component design as well as life cycle. This paper studied the green manufacturing during molding and firing, the green decorative and package design of ceramic products to improve the reclamation rate of production, disassembly and recycle in the life cycle for the decrease of environmental pollution due to wastes.

Abstract: With the development of information technology, 3D printing technology, which is called the symbol of the third industrial revolution and characterized by digitalization, artificial intelligence and new materials application, has brought a revolutionary reform to the future product manufacture. On the basis of the application of 3D printing technology to the ceramic product design, an introduction to the working principle of 3D printing technology and the advantages of its application to the ceramic product design is made, and the influence of 3D printing technology development on the ceramic product design is discussed from four aspects, including design ideas, design models, ceramics designers and product development modes, finally together with a further analysis of the limitations as well as the prospects of the application of 3D printing technology to the ceramic product design.

Abstract: TiC-based cermets with four different components of La₂O₃ content were prepared via vacuum sintering to investigate the effect of La₂O₃ addition on the microstructure and mechanical properties. The microstructure and phase structure were investigated by XRD, SEM, EDS and the mechanical properties were measured. Experimental results show that TiC-based cermets with La₂O₃ addition were also a typical core-rim structure but did not form a new phase. Along with the increase of La₂O₃ content, the density of TiC-based cermets was reduced, EDS analysis revealed La₂O₃ was partly dissolved in the Mo/Ni binder and hindered dissolution and separation of carbides. A moderate amount of La₂O₃ can favor the microstructure refinement and improve its mechanical properties in the form of La₂O₃ particles embedded in Mo/Ni particles. Compared with undoped sample, the cermets doped with 1 wt.% La₂O₃ showed optimum comprehensive properties: the bending strength of 1041.4 MPa, Vickers hardness of 13.19 GPa and the fracture toughness of 14.18 MPa• m^1/2.

Abstract: The digital design of mechanical products is usually first reference existing parts, drawings, and experience to make original design data and design requirements, according to the design of digital model is set up, after an analysis of the finite element model according to the analysis results contrast design goal to design or structure parameter changes, to the expected design purpose. Analysis of the product is an essential part of product design.

Abstract: This manuscript was used to test feasibility that the Al2O3 ceramic composite steel plate was fabricated by Self-propagating High-temperature Synthesis (SHS).The Al2O3 ceramic coatings were prepared on the steel plates.The ceramic coatings had been subsequently characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) attachment. The results showed that the ceramic coatings could be divided into three layers called Al2O3 ceramic layer, Fe/Al2O3 blending layer and iron layer from the roof to the bottom. Al2O3 ceramic layer had many porosities and low density. The tissue structure of Fe/Al2O3 blending layer was compact and had no porosities.

Abstract: The excellent ceramic products of the information age should care for people and design for people. The principles of humanized design for ceramic products include principles giving considerations to both function and comfort, culture and art as well as individuality and pluralism. Besides, those principles should be required to foresee its development trend which manifests in the multiple directions like care for needs, society, environment, physics, sensibility and cultural cognition.

Abstract: This paper presents a method for inter-class ceramic crack detection threshold than the maximum variance within the class-based segmentation. Ceramics crack detection methods are mainly obtained by ceramic image data, image pre-processing, image segmentation, feature extraction and object recognition constitutes five links. Experimental results show that the method can be detected quickly and accurately detect whether the standard ceramic.

Abstract: Composite materials (also called composition materials or shortened to composites) are materials made from two or more constituent materials with significantly different physical or chemical properties, that when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons: common examples include materials which are stronger, lighter or less expensive when compared to traditional materials. Composite materials are generally used for buildings, bridges and structures. The most advanced examples perform routinely on spacecraft in demanding environments.

Abstract: The effects of thickness and impact energy on the medium leakage of composite laminates were discussed in this paper. Impact tests for the composite laminates with the size of 600 mm×700 mm with three different thicknesses were subjected to impact energy levels from 5 J to 40 J. The medium leakage and the damaged area were investigated according to different energy levels and stacking sequences. The damage area was evaluated by visual inspection and three-dimensional microscope. The experimental results reveal that the impact damage of CFRP laminates with three different thicknesses tends to be more severe as impact energy increases. The impact area and the crater depth increases with increasing impact energy. The impact area and the crater depth decreases with increasing thickness for the same impact energy.
