| 1 | 钛板表面激光熔覆锆基合金涂层的组织结构显示文摘 利用激光熔覆技术在Ti板上制备了非晶复合涂层,利用X射线衍射仪、能谱仪、扫描电镜和透射电子显微镜对熔覆层和结合区的组织结构进行了表征。研究发现,熔覆层组织主要由非晶、Zr的金属间化合物、氧化物及局部纳米晶组成。基体与熔覆层结合区由Ti的柱状晶和α(Ti/Zr)固溶体所构成,保证了基体与熔覆层之间有良好的冶金结合。 | 王彦芳 刘忆 李刚 王存山 夏元良 董闯 Sandip Bysakh | 2003 | 复合材料学报2003，20，3： | 6 |
| 2 | Property mapping of polycrystalline diamond coatings over large area显示文摘Large-area polycrystalline diamond(PCD)coatings are important for fields such as thermal management,optical windows,tribological moving mechanical assemblies,harsh chemical environments,biological sensors,etc.Microwave plasma chemical vapor deposition(MPCVD)is a standard technique to grow high-quality PCD films over large area due to the absence of contact between the reactive species and the filament or the chamber wall.However,the existence of temperature gradients during growth may compromise the desired uniformity of the final diamond coatings.In the present work,a thick PCD coating was deposited on a 100-mm silicon substrate inside a 915-MHz reactor;the temperature gradient resulted in a non-uniform diamond coating.An attempt was made to relate the local temperature variation during deposition and the different properties of the final coating.It was found that there was large instability inside the system,in terms of substrate temperature(as high asΔT=212℃),that resulted in a large dispersion of the diamond coating’s final properties:residual stress(-15.8 GPa to+6.2 GPa),surface morphology(octahedral pyramids with(111)planes to cubo-octahedrals with(100)flat top surfaces),thickness(190μm to 245μm),columnar growth of diamond(with appearance of variety of nanostructures),nucleation side hardness(17 GPa to 48 GPa),quality(Raman peak FWHM varying from 5.1 cm^(-1) to 12.4 cm^(-1) with occasional splitting).This random variation in properties over large-area PCD coating may hamper reproducible diamond growth for any meaningful technological application. | Awadesh Kumar MALLIK Sandip BYSAKH Monjoy SREEMANY Sudakshina ROY Jiten GHOSH Soumyendu ROY Joana Catarina MENDES Jose GRACIO Someswar DATTA | 2014 | Journal of Advanced Ceramics2014，3，1： | 4 |
