采用密度泛函理论,利用包含零点能校正的PBE-D3方法研究了5-羟甲基糠醛在双金属催化剂CuPd(111)上表面的加氢还原反应,考虑了两种反应路径,第一种反应路径是侧链上的醛基氧首先发生加氢反应生成F-CHOH中间体,然后F-CHOH中间体继续加氢生成2,5-二羟甲基呋喃;第二种反应路径是侧链上的醛基碳先加氢原还原生成F-CH_(2)O中间体,生成的F-CH_(2)O进一步加氢还原生成2,5-二羟甲基呋喃.计算了两种竞争反应路径的活化能垒和反应热,结果表明,5-羟甲基糠醛在CuPd(111)面加氢还原生成2,5-二羟甲基呋喃的最佳反应路径为:F-CHO→F-CHOH→F-CH_(2)OH.

Influence of cross correlation step length on the surface stress of thin laser cladding Fe314 alloy coatings

引用

International Journal of Minerals,Metallurgy and Materials 2012年第6期19卷 549-554页

作者： Bin Liu shi-yun Dong Bin-shi Xu Peng He State Key Laboratory of Advanced Welding and Joining Harbin Institute of Technology Harbin 150001 China National Key Laboratory for Remanufacturing Academy of Armored Forces Engineering Beijing 100072 China

To measure the surface stress of thin laser cladding coatings with Rayleigh waves based on the cross correlation function, this pa- per introduced the influence of cross correlation step length on the stress measurement. Flat-shaped specimens made of laser cladding Fe314 alloy coatings were performed by static tensile tests, and Rayleigh wave signals were collected during the test process with an ultrasonic pulser and receiver instrument combined with two Rayleigh wave transducers. The difference in time of flight between two signals was de- termined based on the cross correlation function. The microstructure was observed by scanning electronic microscopy. The influence of the stress on the propagation velocity of Rayleigh waves and the relationship between the difference in time of flight and tensile stress under dif- ferent cross correlation step lengths were analyzed. The inhomogeneous deformation of the coatings affects the relationship between the dif- ference in time of flight and tensile stress; the stress measurement of the coatings is nearly constant with the increase of cross correlation step length when it attains one cycle.

中国有色金属学会会刊：英文版 2004年第z1期14卷 182-185页

作者： DONG shi-yun XU Bin-shi MA shi-ning TU Wei-yi National Key Laboratory for Remanufacturing Academy of Armored Force Engineering Beijing 100072 China National Key Laboratory for RemanufacturingAcademy of Armored Force Engineering Beijing 100072 China National Key Laboratory for RemanufacturingAcademy of Armored Force Engineering Beijing 100072 China National Key Laboratory for RemanufacturingAcademy of Armored Force Engineering Beijing 100072 China

Nanoparticle reinforced nickel matrix composite coatings, such as n-Al2O3/Ni, n-SiO2/Ni, n-SiC/Ni and n-TiO2/Ni, were fabricated by brush plating technique. Hardness, wear resistance and contact-fatigue resistance of the composite coatings were determined, and strengthening mechanism of the composite coatings was discussed. Results show that the composite coatings have superior properties to the Ni metal coating. Compared with properties of brush plated Ni metal coating, the composite coatings have hardness over 1.5 times and wear resistance capability of about 2.5 times. The strengthening mechanism of the composite coatings mainly includes fine-crystal grain effect, nanoparticle dispersion effect and dislocation effect.
