Liquid Deposition

Metal colloids in 2-mercaptoethanol using nanoparticles (NPs) of iron (Fe), cobalt (Co), and nickel (Ni) were prepared by chemical liquid deposition method. Transmission electron microscopy, electron diffraction, UV-VIS spectroscopy, and scanning electron microscopy with electron dispersive X-ray spectroscopy characterized the resulting colloidal dispersions. The NPs exhibited sizes with ranges from 9.8 nm for Fe, 3.7 nm for Co, and 7.2 nm for Ni. The electron diffraction shows the presence of the metals in its elemental state Fe (0), Co (0), and Ni (0) and also some compounds FeO (OH), CoCo2S4, and NiNi2S4.

Abstract A new solid free-form fabrication (SFF) technique, named Physical and Chemical Liquid Deposition (P/CLD), is introduced in this paper, and then several key technical problems are stated. In order to solve these problems, theoretical models to describe the nucleation and growth of deposits in PLD, the chemical dynamic process in CLD, and the heat transfer in P/LCD are studied. To determine the heat transfer parameters, some experiments are designed and experimental results are presented.

Abstract Most technologies used in fabrication of MEMS involve very sophisticated and expensive processes, which limit the application of MEMS greatly. This paper presents our research on a new manufacturing technology named Selective Chemical Liquid Deposition for Mini-structures and Microsystems SCLD-MSMS. In SCLD-MEMS, small droplets of solution or liquid reactant are ejected from a nozzle at room temperature, the droplets decompose or react with each other after impinging upon a hot substrate, the reacted solid products will then deposit on the substrate. By controlling the droplet size, the flow rate, the motion of the nozzle, and the temperature of the substrate, as well as other process parameters, a desired 3-D microstructure of deposited material can be formed through layer-by-layer scanning technique. The working principle and some experiment results are discussed in this paper.
