Recently, requirements for structural materials become increasingly severe. A coating process is one of the most promising methods to achieve the requirements. However, conventional coating processes generally have following major technical problems. We develop Supersonic Free-Jet PVD (SFJ-PVD) as a new coating process to solve the problems. The SFJ-PVD is a technique to deposit nanoparticles with supersonic gas flow and to form a thick coating film without a crack or a void. This method is composed of "gas evaporation" and "vacuum deposition". In a gas evaporation chamber, a source material is evaporated to form nanoparticles in an inert gas atmosphere. The nanoparticles are then carried to a substrate in a deposition chamber with an inert gas flow through a transfer pipe. The gas flow is generated by the pressure difference between the chambers and accelerated through a specially designed supersonic nozzle at the supersonic flow of 4.2 Mach, number. With SFJ-PVD, We produce metal films and ceramic films that have smooth, compact and defect-free microstructure both in the film and at the interface between the substrate and the film and excellent adhesive strength to the substrate.

最近，对结构材料的要求越来越严重。涂料过程是达到要求的最有前途的方法之一。但是，常规涂料工艺通常存在重大技术问题。我们开发超音速自由喷气PVD（SFJ-PVD）作为解决问题的新涂料过程。 SFJ-PVD是一种用超音速气流沉积纳米颗粒并形成没有裂缝或空隙的厚涂层的技术。该方法由“气体蒸发”和“真空沉积”组成。在气体蒸发室中，蒸发材料在惰性气气大气中形成纳米颗粒。然后将纳米颗粒带到沉积室中的底物，并带有通过转移管道的惰性气体流动。气流是由腔室之间的压力差产生的，并通过4.2马赫的超音速流动，通过特殊设计的超音速喷嘴加速。使用SFJ-PVD，我们生产金属膜和陶瓷膜，在膜中以及基板和膜之间的界面以及底物的出色粘合强度上都具有光滑，紧凑和无缺陷的微观结构。
