SBIR Phase I: Study of Macroparticle Growth and Its Effect on Relatively Thick Functional Physical Vapor Deposition (PVD) Coatings

9860404 这个小型企业创新研究（SBIR）第一阶段项目提出了一种新的物理气相沉积（PVD）替代传统电镀用于沉积相对较厚的功能性金属涂层。众所周知，电镀操作会产生大量的危险废物和有毒烟雾。 PVD方法将减少液体化学品的使用，原位回收固体金属，并且不会产生任何排放。 该概念是以高速率进行金属的非现场线沉积，这将允许从所有侧面同时在三维物体上生长相对厚（大于10微米）且均匀的金属沉积物。 以这种方式，可以在相对短的时间内存款大量的小物体或少量的大物体。 第一阶段将探讨工艺参数对降解生长膜中的夹杂物和这种厚膜的完整性的影响。 将使用实验的统计设计进行过程建模。 Chrome、铜、镍和其他相对较厚的涂层广泛用于国防、电子、航空航天和汽车工业。 预计将以环境安全的方式沉积高质量、厚的功能性金属涂层。

9860404 This Small Business Innovation Research (SBIR) Phase I project proposes a novel physical vapor deposition (PVD) alternative to conventional electroplating used in depositing relatively thick functional metal coatings. Electroplating operations are known to generate large quantities of hazardous waste and toxic fumes. The PVD approach will obviate the use of liquid chemicals, recycle solid metals in situ, and leave no emissions. The concept is a non-line-of-site deposition of metals at high rates, which will allow the growth of relatively thick (greater than 10 microns) and uniform deposits of metals on three-dimensional objects simultaneously from all sides. In this way, it may be possible to deposit a large number of small objects or a small number of large objects in a relatively short period. Phase I will explore the effect of process parameters on degrading inclusions in the growing film and the integrity of such thick films. Process modeling, using the statistical design of experiments, will be performed. Chrome, copper, nickel, and other relatively thick coatings are extensively used in the defense, electronics, aerospace, and automotive industries. It is anticipated that high quality, thick functional metal coatings will be deposited in an environmentally safe manner.
