Zhang Jian, female, born in July, 1963, Ph.D., graduated from Northeastern University, majoring in mechanical design and theory, and now teaches at the School of Mechanical Engineering, Shenyang University of Technology. Mainly engaged in, mainly engaged in surface modification and friction and wear research. During my master's degree, I successfully completed the scientific research project sponsored by my tutor: Research on the Mechanism and Method of Non-grinding Gear Running-in, which was funded by the National Natural Science Foundation, and published six papers on this topic as the first author. Among them, EI Engineering of the United States searched the influence of chemical running-in on surface contact fatigue life and the influence of chemical running-in on tooth surface bonding published in Tribology Journal. As the first participant, he participated in the research on friction and wear mechanism and application of plasma arc quenching surface funded by Liaoning Education Science Fund. As the third participant, he participated in the project "Development of special coupling device for electric submersible pump oil production system" funded by Liaoning Education Science Fund, and won the third prize of provincial scientific and technological research achievement appraisal and Liaoning scientific and technological progress. In addition, he also participated in five horizontal projects such as the design of CNC hot machining center for armored vehicle repair parts in shenyang military area command Equipment Department. Six papers on plasma arc quenching have been published. Project undertaking: experimental design and tribology research.
