| 1 | Effect of Laser Remelting on the Microstructure and Corrosion Resistance of Plasma Sprayed Fe-based Coating显示文摘Fe-based amorphous and nanocrystalline coatings were fabricated by air plasma spraying. The coatings were further treated by laser remelting process to improve their microstructure and properties. The corrosion resistance of the as-sprayed and laser-remelted coatings in 3.5wt% Na Cl and 1 mol/L HCl solutions was evaluated by electrochemical polarization analysis. It was found that laser-remelted coating appeared much denser than the as-sprayed coating. However, laser-remelted coating contains much more nanocrystalline grains than the as-sprayed coatings, resulting from the lower cooling rate in laser remelting process compared with plasma spraying process. Electrochemical polarization results indicated that the laser-remelted coating has great corrosion resistance than the as-sprayed coating because of its dense structure. | 姜超平 WANG Junxing HAN Jianjun LU Yuan XING Yazhe CHEN Yongnan SONG Xuding | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，4： | 6 |
| 2 | Effects of Heat-treatment on Crystallization and Wear Property of Plasma Sprayed Fe-based Amorphous Coatings显示文摘The Fe-based amorphous coatings were produced by air plasma spraying. The as-sprayed coatings were heat-treated at the temperature of 573, 873, and 1 023 K, respectively. The crystallization and wear behavior of the heat-treated amorphous coatings were investigated. It was found that the amorphous-nanocrystalline transformation appeared when the as-sprayed coatings were treated at 853 K. The crystallization process had completed and a coating with microcrystallines was formed when the treatment temperature reached 1 023 K. The resultant amorphous and nanocrystalline composite coatings exhibited superior wear resistance compared to crystalline coating. It is attributed to fine grain strengthening of formed nanocrystallines. | 姜超平 XING Yazhe HAO Jianmin SONG Xuding | 2013 | Journal of Wuhan University of Technology(Materials Science)2013，28，4： | 3 |
| 3 | Hybrid Visual Servoing Control for Robotic Arc Welding Based on Structured Light Vision显示文摘A novel hybrid visual servoing control method based on structured light vision is pro-posed for robotic arc welding with a general six degrees of freedom robot. It consists of a positioncontrol inner-loop in Cartesian space and two outer-loops. One is position-based visual control inCartesian space for moving in the direction of weld seam, i.e., weld seam tracking, another is image-based visual control in image space for adjustment to eliminate the errors in the process of tracking.A new Jacobian matrix from image space of the feature point on structured light stripe to Cartesianspace is provided for dierential movement of the end-e?ector. The control system model is simplifiedand its stability is discussed. An experiment of arc welding protected by gas CO2 for verifying iswell conducted. | XUDe WANGLin-Kun TUZhi-Guo TANMin | 2005 | 自动化学报2005，31，4： | 2 |
| 4 | OstMAPKKK5, a truncated mitogen-activated protein kinase kinase kinase 5, positively regulates plant height and yield in rice显示文摘Rice(Oryza sativa L.)is a major food crop worldwide.Plant height and yield are important agronomic traits of rice.Several genes regulating plant height and/or yield have been cloned.However,the molecular mechanisms coordinating plant height and yield are not fully characterized.Here,we report a novel gene,OstMAPKKK5 that encodes a truncated variant of a mitogen-activated protein kinase kinase kinase 5(OsMAPKKK5)lacking an intact kinase domain.Transgenic plants overexpressing OstMAPKKK5 in indica cultivar 9311 showed increased plant height,grain length,grain width,1000-grain weight,grain number per main panicle,and yield.Real-time quantitative PCR showed that OstMAPKKK5 was widely expressed in various tissues and developmental stages.The increased plant height and yield were attributed to enlarged cell size.Overexpression of OstMAPKKK5 led to higher contents of various forms of endogenous gibberellin(GA),especially the most common active forms,GA1,GA3,GA4.We concluded that OstMAPKKK5 positively regulates plant height and yield in rice by affecting cell size,and that its underlying mechanism is based on increased endogenous GA content. | Yahui Liu Yu Zhu Xuding Xu Fan Sun Jingshui Yang Liming Cao Xiaojin Luo | 2019 | The Crop Journal2019，7，5： | 2 |

| 18 | Spheroidization behavior of dendritic b.c.c. phase in Zr-based β-phase composite显示文摘The spheroidization behavior of the dendritic b.c.c. phase dispersed in a bulk metallic glass (BMG) matrix was investigated through applying semi-solid isothermal processing and a subsequent rapid quenching procedure to a Zr-based β-phase composite. The Zr-based composite with the composition of Zr56.2Ti13.8Nb5.0Cu6.9Ni5.6Be12.5 was prefabricated by a water-cooled copper mold-casting method and characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The results show that the composite consists of a glassy matrix and uniformly distributed fine dendrites of the β-Zr solid solution with the body-centered-cubic (b.c.c.) structure. Based on the differential scanning calorimeter (DSC) examination results, and in view of the b.c.c. β-Zr to h.c.p. α-Zr phase transition temperature, a semi-solid holding temperature of 900℃ was determined. After reheating the prefabricated composite to the semi-solid temperature, followed by an isothermal holding process at this temperature for 5 min, and then quenching the semi-solid mixture into iced-water; the two-phase microstructure composed of a BMG matrix and uniformly dispersed spherical b.c.c. β-Zr particles with a high degree of sphericity was achieved. The present spheroidization transition is a thermodynamically autonomic behavior, and essentially a diffusion process controlled by kinetic factors; and the formation of the BMG matrix should be attributed to the rapid quenching of the semi-solid mixture as well as the large glass-forming ability of the remaining melt in the semi-solid mixture. | Sun Guoyuan Li Ping Chen Wei Song Xuding | 2013 | China Foundry2013，10，2： | 1 |
