| 中文摘要: |
| 超音速火焰(High Velocity Oxy -Fuel，简称HVOF)喷涂具有高速和相对较低的温度两个重要特征，能够获得比普通火焰喷涂或等离子喷涂(Plasma Spray，简称PS)结合强度更高的致密涂层。纳米材料具有独特的表面效应、体积效应及量子尺寸效应，其电学、力学、磁学、光学和热学等性能产生了惊人的变化。随着材料科学技术的深入发展，在实际生产和生活中运用性能优良的纳米材料倍受人们关注，其中，采用热喷涂技术制备纳米结构涂层是构筑纳米结构材料的最具前途的方法之一。从目前国内外的情况来看，HVOF喷涂纳米结构涂层技术的研究取得了较大的进展。综合国内外文献，总结了HVOF喷涂制备纳米结构涂层的研究现状，着重阐述了热喷涂纳米涂层的基本过裎和结合机理，指出了利用HVOF喷涂纳米结构涂层存在的问题，并对热喷涂纳米结构涂层的发展前景作了展望。 |
| 英文摘要: |
| Featured with very high particle velocities and relatively low particle temperatures as compared to those in the plasma spray process and other oxy-fuel thermal spray, the HVOF thermal spray provides a efficient way to produce higher adhesion dense coatings. The nanometer materials has greatly changed material properties of electronics, mechanics, magnetics, thermodynamics and optics due to their unique surface, volume and quantum size effects. Further development of nanaomaterials technology will be focused on their engineering application. The thermal spraying process is considered as a most promising method for fabricating nanostructured materials. Great progress of fabricating nanostructured by HVOF has been made according to the situation home and abroad. From domestic to foreign literatures, the research present of nanostructured coating prepared by HVOF was analyzed, the forming and combination mechanism of nanostructured coatings were also elaborated, and the existent question using HVOF thermal spray was pointed out. The bright prospect of fabricating nanostructured coatings by HVOF was preconceived. |
