Contributed by the Manufacturing Engineering Division of ASME for publication in the JOURNAL OF MICRO- AND NANO-MANUFACTURING. Manuscript received October 15, 2016; final manuscript received June 14, 2017; published online September 28, 2017. Assoc. Editor: Cheryl Xu.

J. Micro Nano-Manuf 5(4), 044501 (Sep 28, 2017) (5 pages) Paper No: JMNM-16-1062; doi: 10.1115/1.4037473 History: Received October 15, 2016; Revised June 14, 2017

The importance of coatings in modern science and industry is great, and the system presented in this manuscript attempts to provide a method of creating high quality nanoparticle coatings with in situ sintering of nanoparticles. Dual regime nozzle creates close to optimum conditions for particle delivery and deposition and the addition of in situ thermally assisted coating makes it more productive. Preliminary results show systems uniform coating and in situ sintering capability.
