Synthesis and properties of 0.3%Y₂O₃/0.3%La₂O₃/0.3%Al₂O₃/Cu composite

Science and Engineering of Composite Materials (2013)

Song Wang Ming Xie Jiming Zhang Yongtai Chen

Abstract The 0.3%Y 2 O 3 /0.3%La 2 O 3 /0.3%Al 2 O 3 /Cu composite was prepared by oxygen and nitrogen atomization spray deposition technique, internal oxidation, and then treated by annealing at different temperatures. Physical properties such as microstructures, fracture appearance, hardness, strength, electrical conductivity, and arc erosion surface of the composite were investigated. The experimental results show that with an increase in the annealing temperature, the grains of the composite grow up obviously and the electrical conductivity of the composite increases gradually, while the hardness and the tensile strength decrease. When the annealing temperature reaches 1000°C, the matrix grains begin to appear as annealing twins. The tensile fracture morphology of the composite that has been treated by annealing at 700°C for 2 h shows a huge number of large and deep dimples, in which the metallic oxide particles exist. The fracture mode of the composite is the microporous polycondensation plastic fracture. The arc erosion surface shows a large number of paste-like coagulum and bubbles.

Fracture Characteristics of 9%Ni Steel at Low Temperature

Qingren Xiong Chunyong Huo Shaotao Gong Jinheng Luo Jiming Zhang

The fracture characteristics of several types of tensile specimens of 9%Ni steel at low temperature was studied, and the Notch (Crack) Sensitivity and Notch (Crack) Relative Strength decreased (increased) Ratio of notch (crack) specimen were studied, while the crack preparation method of the crack specimen was discussed. The results indicate that the Notch (Crack) Sensitivity and Notch (Crack) Relative decreased (increased) Ratio can be used to evaluate the low temperature low stress brittle fracture resistance of the material. 9%Ni steel has good brittle fracture resistance at low temperature. The crack preparation principle of the crack tensile specimen was put forward.

Synthesis of novel ECH crosslinked chitosan schiff base-sodium alginate for adsorption of Cd(II) ion from aqueous solution

Desalination and Water Treatment (2019)

Weili Wang Qi Lu Xiaoliang Ren Canxiang Liu Juan Jin

A novel chitosan derivative was synthesized by crosslinking reaction of chitosan Schiff base and sodium alginate, and then used as adsorbent for Cd(II) ion.The structure of chitosan derivative was fully characterized and the adsorption behavior of Cd(II) ion was also investigated.The equilibrium and kinetic data fitted well the Langmuir and pseudo-second-order model.The estimated maximum adsorption capacity is 262.47 mg/g.Thermodynamic parameters indicates that at higher temperatures, the process is spontaneous, hence the adsorption is easy.Additionally, the regenerated adsorbent after five cycles could retain 87.15% of the adsorption capacity compared with the freshly prepared adsorbent.

Research on leak detection of vials based on tunable diode laser absorption spectroscopy technology

Keke Zhang Li Fei-Fei Shixuan Liu Shizhe Chen Shuwei Zhang

The off-line sampling destructive test is often used in the seal integrity test of vials, which has the disadvantages of long time consuming, low accuracy and high missing rate. In order to solve the above problems, the tunable diode laser absorption spectroscopy technology and wavelength modulation spectroscopy technology are used to measure the oxygen concentration in the vials. The ratio method of second harmonic and first harmonic is used to eliminate the influence of the rapid change of light intensity. The experimental results show that the system can complete the seal integrity detection of 300 vials per minute. This method belongs to the non-destructive online detection mode, which can realize the fast detection of vials without interference.

Research on Vision Accurate Positioning and Algorithm of Automatic Maintenance Robot for Unmanned Power Distribution Room

2022 IEEE 4th International Conference on Civil Aviation Safety and Information Technology (ICCASIT) (2022)

Jiming Zhang Xianquan Xu Jing Xu Sheng Xia

This paper explores the design and implementation of automatic maintenance robot control system for unmanned power distribution room. This paper studies the machine vision technology of the distribution and substation operation robot. At the same time, this paper adopts the adaptive threshold segmentation method based on image brightness adjustment and optimization to improve the high robustness of the automatic maintenance robot's visual positioning and recognition method.
