In situ Functionally Gradient Coatings Using the Combustion Chemical Vapor Deposition Method

燃烧化学气相沉积(CCVD(SM))是由首席研究员发明的一种高质量的薄膜沉积技术，可以廉价、快速、连续地应用于各种材料。该技术可用于生产功能梯度材料。CCVD方法具有成本低、质量高、通用性强等特点。它不需要反应室或炉子，但所生产的薄膜在质量上与CVD薄膜相当，并且CCVD技术允许衬底通过沉积区用于生产线或大面积涂层。此外，很容易进行构图更改。CCVD，Inc.已经在没有炉子或反应室的开放大气中生产了多种材料的CVD质量薄膜，重点是YSZ。功能梯度材料(FGM)系统具有良好的耐磨性、耐热性和耐腐蚀性，其外涂层为一种新颖的薄膜。将使用CCVD分别生长FGM系统组件的薄膜，并且薄膜的化学计量、形貌、微结构和物理性能将作为沉积条件的函数来确定。然后，将结合刚刚完善的CCVD技术和耐磨性测试来创建功能梯度材料涂层。

Combustion chemical vapor deposition (CCVD(SM)), which was invented by the principal investigator, is a high quality film deposition technique that can inexpensively and quickly apply various materials in a continuous manner. This technology can be used for the production of functionally gradient materials. The CCVD method is low cost, high quality and versatile. It does not require a reaction chamber or furnace, yet the thin films produced are comparable in quality to CVD films, and CCVD technology allows substrates to be passed through a deposition zone for production line or large area coatings. Also, composition changes are easily made. CCVD, Inc., has produced CVD quality films of numerous materials, with an emphasis on YSZ, in the open atmosphere without a furnace or reaction chamber. The functionally gradient material (FGM) system with good abrasion, heat and corrosion resistance has a novel thin film as the exterior coating. Films of the FGM system components will be grown separately using CCVD, and the stoichiometry, morphology, microstructure, and physical properties of the films will be determined as a function of deposition conditions. The FGM coating will then be created by combining the CCVD techniques just perfected and tested for wear resistance.
