| 1 | Relationship of microstructure transformation and hardening behavior of type 17-4 PH stainless steel显示文摘The relationship between the microstructure transformation of type 17-4 PH stainless steel and the aging hardening be- havior was investigated. The results showed that, when 17-4 PH stainless steel aging at 595°C, the bulk hardness of samples attains its peak value (42.5 HRC) for about 20 min, and then decreases at all time. TEM revealed the microstructure corresponding with peak hardness is that the fine spheroid-shape copper with the fcc crystal structure and the fiber-shape secondary carbide M23C6 precipitated from the lath martensite matrix. Both precipitations of copper and M23C6 are the reasons for strengthening of the alloy at this tem- perature. With the extension of holding time at this temperature, the copper and secondary carbide grow and lose the coherent rela- tionship with the matrix, so the bulk hardness of samples decreases. | Jun Wang Hong Zou Cong Li Ruling Zuo Shaoyu Qiu Baoluo Shen | 2006 | Journal of University of Science and Technology Beijing2006，13，3： | 10 |

| 3 | Improvement of tribological behavior of a Ti-Al-V alloy by nitrogen ion implantation显示文摘The tribological properties especially wear and hardness of a Ti-Al-V alloy with nitrogen implantation (energy 60 keV) were investigated. The implantation was carried out at fluences range from 1×1016 to 4×1017 ions/cm2. Glancing angle X-ray diffraction (GAXRD) and X-ray photoelectron spectroscopy (XPS) analyses were performed to obtain surface characterization of the implanted sample. The unimplanted and implanted samples were also annealed at 600 ℃ in order to understand the influence of annealing on the tribological properties of Ti-Al-V. The hardness shows significant improvement at the higher fluence. After annealing at 600 ℃, the friction coefficient exhibits a relative decrease for the nitrogen-implanted samples. In addition, the wear rates of the implanted samples exhibits a great decrease after annealing at 600 ℃. Nature of the surface and reason for the variation and improvement in wear resistance were discussed in detail. | LIU Yanzhang ZU Xiaotao QIU Shaoyu HUANG Xinquan | 2006 | Rare Metals2006，25，z1： | 2 |

| 13 | Monitoring the delicate operations of surgical robots via ultra-sensitive ionic electronic skin显示文摘The arrival of surgical robots in high-end medical equipment is a landmark,and the realization of tactile sensation a major challenge in this important cutting-edge research field.Aiming to address this issue,we present ultra-sensitive ionic electronic skin in the form of flexible capacitive pressure sensors,which incorporate multistage bionic microstructures in ion gels for the purpose of monitoring the delicate operations of surgical robots.Significantly,the ionic skin exhibits an ultra-high sensitivity of 9484.3 kPa^(-1)(<15 kPa),and the sensitivity remains higher than 235 kPa^(-1)in the wide range of 15-155 kPa.The device has also achieved a detection limit as low as 0.12 Pa or,equivalently,0.31 mg,fast response within 24 ms,and high robustness(loading/unloading for 5000 cycles without fatigue).The sensor facilitates the challenging task of tele-operated robotic threading,which exceeds the human tactile perception limit when threading a needle.We have also confirmed that ionic skin can be used in robot-assisted invasive surgery,such as incision/resection of tissues and suturing of wounds,providing tactile information to surgeons to improve operation success rates.The flexible ionic skin is capable of conforming to the various shapes of robotic manipulators,thus has great promise for applications in robotic dexterous manipulation,prosthetics and human-machine interfaces. | Danyang Wei Jiajie Guo Yuqi Qiu Shaoyu Liu Jiangyan Mao Yutian Liu Zhenbing Chen Hao Wu Zhouping Yin | 2022 | National Science Review2022，9，12： | 0 |
