With the use of the well-controlled thermal plasma reactor based on the newly designed forced constricted type dc plasma jet generator, application feasibility for advanced materials fine process is studied, mainly functionally graded coatings (FGC) of hydroxyapatite (HAP). Findings are as follows:1. The image spectroscopic system composed of a double wavelength optical system and the gated ICCD camera has been developed. This system can measure two dimensional temperature distribution and parameters of injected spraying particles. Relationship between parameters of injected spraying particles and quality of prepared films is discussed.2. Preparation of Ti-HAP FGC films are studied under various spraying conditions. The adhesion strength, the Vickers hardness, c-axis orientation and the porosity of prepared FGC films are well controlled with spraying conditions. Simulated body fluid test of HAP coatings is also discussed and apatite is newly formed on the surface of the coatings.3. A continuous synthesis method to produce carbon nanofibers (CNFs) including multi-walled carbon nanotubes is studied. CNFs production using catalyst powders (Fe, Ni) is more enhanced compared to that using only CH_4/H_2 gas mixtures.4. Plasma spray gun has been newly designed as dual anode type plasma spray gun which can generate stable and high power plasma jets for a long time at various operating conditions. Using this, under laminar plasma jets in the air, TiO_2 powders with anatase and rutile types mixtures are directly and effectively synthesized from raw Ti powders.

利用基于新设计的强制收缩式直流等离子体射流发生器的可控热等离子体反应器，研究了先进材料精细加工的应用可行性，主要是羟基磷灰石（HAP）功能梯度涂层（FGC）。研究结果如下： 1．研制了由双波长光学系统和门控ICCD相机组成的图像光谱系统。该系统可以测量喷射喷涂颗粒的二维温度分布和参数。讨论了喷射喷涂粒子的参数与制备的薄膜质量的关系。 2．研究了不同喷涂条件下 Ti-HAP FGC 薄膜的制备。制备的FGC薄膜的粘附强度、维氏硬度、c轴取向和孔隙率都可以通过喷涂条件得到很好的控制。并对HAP涂层的模拟体液试验进行了讨论，涂层表面新生成了磷灰石。 3．研究了生产包括多壁碳纳米管的碳纳米纤维（CNF）的连续合成方法。与仅使用CH_4/H_2气体混合物相比，使用催化剂粉末（Fe、Ni）的CNFs产量得到了更大的提高。4．等离子喷枪全新设计为双阳极型等离子喷枪，可在各种工况下长时间产生稳定、高功率的等离子射流。利用该方法，在空气中的层流等离子体射流下，由Ti粉原料直接有效地合成锐钛矿型和金红石型混合物的TiO_2粉末。
