The objective of this program was to design and develop a novel hybrid coating technology and related infrastructure for the synthesis of soft phase and hard phase nano particle composite coatings. The project successfully completed design, development and testing of the following two major technologies 1 Electrostatic coating ESC set up for the deposition of solid lubricant as well as hard phase nano particles 2 Chemical vapor infiltration CVI for depositing binder in the porous matrix. The investigators have successfully developed and tested the ESC system for coating lubricant as well as hard nano particles on large areas and complex shapes, and have completed fabrication and testing of the CVI set up. To demonstrate the success of completion of the project, the team has deposited ZnO 0-20 nm as well as MoS2 0-700 nm nano particles as soft lubricant materials and cBN as hard phase material using ESC on complex geometries carbide insert samples and has demonstrated TiN infiltration. The research opened many new opportunities to realize practical combinatorial coatings for the next generation of Air Force, Department of Defense DoD devices and systems.
