| 1 | Influence of Substrate Negative Bias on Structure and Properties of TiN Coatings Prepared by Hybrid HIPIMS Method显示文摘TiN coatings were deposited using a hybrid home-made high power impulse magnetron sputtering(HIPIMS)technique at room temperature.The effects of substrate negative bias voltage on the deposition rate,composition,crystal structure,surface morphology,microstructure and mechanical properties were investigated.The results revealed that with the increase in bias voltage from-50 to-400 V,TiN coatings exhibited a trend of densification and the crystal structure gradually evolved from(111) orientation to(200)orientation.The growth rate decreased from about 12.2 nm to 7.8 nm per minute with the coating densification.When the bias voltage was-300 V,the minimum surface roughness value of 10.1 nm was obtained,and the hardness and Young's modulus of TiN coatings reached the maximum value of 17.4 GPa and 263.8 GPa,respectively.Meanwhile,the highest adhesion of 59 N was obtained between coating and substrate. | Zhenyu Wang Dong Zhang Peiling Ke Xincai Liu Aiying Wang | 2015 | Journal of Materials Science & Technology2015，31，1： | 10 |
| 2 | Coal and gas outburst prevention using new high water content cement slurry for injection into the coal seam显示文摘As coal and gas outburst is one of the most serious mine disasters, it is very important to at least control it if not prevent it from occurring. Injecting cement slurry or grouting into the coal seam can strengthen the seam, increase its rigidity coefficient(f), and reduce the volumetric expansion due to gas energy release.This paper reports the results of laboratory experiments on cement-based high water content slurry having different water-cement ratios(W/C) to be used for coal injection. The results show that as the W/C increases, the mobility of the slurry and its setting time increase. The compressive strength and rupture strength, however, are reduced. Furthermore, high W/C grout shows early strength after 7 days, which can be 80% of its 14-day compressive strength. To achieve rapid setting and early strength, the addition of Na_2SiO_3has proven to give the best result, when the concentration of the additive is 3%. The initial and final setting times are 13 and 21 min shorter than samples without Na_2SiO_3, while the compressive strength is more than double. As a retarder, the initial setting time can be extended to 83 min when tartaric acid of 0.4% concentration is added. Through the orthogonal experiment, the optimum recipe of the new high water content slurry has been determined to be: W/C = 2, tartaric acid = 0.2%, Na_2SiO_3= 3%, and12% bentonite. Reinforcement by injection simulation experiments show that the grouting radius of the new slurry mix is 250 mm when the applied grouting pressure is 60 k Pa, 7-day rupture strength and compressive strength are 5.2 and 6.4 MPa, respectively, and are 37% and 88% higher than ordinary cement grout. It can be concluded that the newly developed slurry mix is more effective than the ordinary mix for reinforcing coal and controlling gas outburst. | Zhou Peiling Zhang Yinghua Huang Zhi'an Gao Yukun Wang Hui Luo Qiang | 2017 | International Journal of Mining Science and Technology2017，27，4： | 3 |
| 3 | Microstructure and Tribological Behavior of Self-lubricating(Si:N)-DLC/MAO Coatings on AZ80 Magnesium Substrate显示文摘The combined micro arc oxidation(MAO)and a hybrid beam deposition process was used to deposit duplex(Si:N)-DLC/MAO coatings on AZ80 magnesium alloy.The microstructure and composition of the duplex coatings were analyzed by Raman spectroscopy,X-ray photoelectron spectroscope(XPS),scanning electron microscope(SEM)and atomic force microscopy(AFM).Tribological behaviors of the coatings were studied by ball-on-disk friction test.It was found that the ID/IG ratio of the(Si:N)-DLC(diamond-like carbon)top films increases with decreasing C2H2/N2ratio.The(Si:N)-DLC top film with Si3N4was formed on the MAO coated sample as the C2H2/N2ratio was 10sccm:5sccm,which showed an increasing critical load compared with the pure DLC directly deposited on the Mg alloy substrate.As a result,the(Si:N)-DLC/MAO coating exhibited an advanced wear protection for the substrate. | Wei YANG Zhennan DENG Dong ZHANG Peiling KE Aiying WANG | 2013 | Acta Metallurgica Sinica(English Letters)2013，26，6： | 2 |

| 7 | A Singular Value Thresholding Based Matrix Completion Method for DOA Estimation in Nonuniform Noise显示文摘Usually,the problem of direction-of-arrival(DOA)estimation is performed based on the assumption of uniform noise.In many applications,however,the noise across the array may be nonuniform.In this situation,the performance of DOA estimators may be deteriorated greatly if the non-uniformity of noise is ignored.To tackle this problem,we consider the problem of DOA es-timation in the presence of nonuniform noise by leveraging a singular value thresholding(SVT)based matrix completion method.Different from that the traditional SVT method apply fixed threshold,to improve the performance,the proposed method can obtain a more suitable threshold based on careful estimation of the signal-to-noise ratio(SNR)levels.Specifically,we firstly employ an SVT-based matrix completion method to estimate the noise-free covariance matrix.On this basis,the signal and noise subspaces are obtained from the eigendecomposition of the noise-free cov-ariance matrix.Finally,traditional subspace-based DOA estimation approaches can be directly ap-plied to determine the DOAs.Numerical simulations are performed to demonstrate the effective-ness of the proposed method. | Peiling Wang Jinfeng Zhang | 2021 | Journal of Beijing Institute of Technology2021，30，4： | 1 |
