| 中文摘要: |
| 冷喷涂是基于空气动力学原理的一种新型喷涂技术。它是利用低温（一般低于6000C）超音速气体射流加速喷涂粒子，使粒子不熔化，以固态形式与基体发生塑性碰撞而实现涂层沉积。相比于热喷涂技术，冷喷涂可以避免材料在喷涂过程中发生过热、氧化、晶粒长大等现象，适用于非晶、纳米晶涂层的制备。介绍了冷喷涂技术的原理、特点、沉积机制和工艺参数，总结了冷喷涂纳米涂层的研究进展。 |
| 英文摘要: |
| A new spraying technology called Cold Gas Dynamics Spraying process ( CGDS) , is developed based on aerodynamics recent years. It uses a low temperature supersonic gas jet ( typically below 600℃ ) to accelerate unmelted solid powders over a critical velocity at which particles impact on the substrate , deform plastically and mechanically to form the coating. Comparing with thermal spraying processes, CGDS may minimize any changes of the micro-structure, such as over-heated, oxidation and grain growing-up. The principles, features, mechanisms and parameters of the CGDS were presented. The research processes on cold-sprayed nano-structured coatings were involved. |
