SELF-LUBRICATING PLASMA-SPRAYED COMPOSITES FOR SLIDING-CONTACT BEARINGS TO ° C by Harold E. Sliney Lewis Research Center SUMMARY Plasma-sprayed self-lubricating coatings were investigated for possible use to ° C in Space Shuttle airframe bearings or other high-temperature applications such as automotive turbine regenerator by: 2. A WC–Co coating with self-lubricating property was deposited by detonation gun (D-gun) process, using a commercial WC–Co powder doped with a MoS2–Ni powder, under a proper spray condition. @article{osti_, title = {Composition optimization of chromium carbide based solid lubricant coatings for foil gas bearings at temperatures to C.

In this study, two kinds of NiCr/Cr3C2-BN composite powders were prepared with individual cladding (FKBN) and low pressure spray granulation (YLBN) methods, and the derived NiCr/Cr3C2-BN coatings were fabricated by plasma spraying technology. The microstructure, mechanical and tribological properties of the two coatings were systematically by: 2. Coatings were made by plasma spray method and %8 Y-PSZ was used as coating material. Wear tests were done by pin-on-disc method with three different load parameters and results were discussed. Bearings industry. See also what's at your library, or elsewhere.. Broader terms: Machine parts industry; Bearings (Machinery) Used for: Bearings (Machinery) -- Trade and manufacture.   Atmospheric plasma-sprayed (APS), low-friction Al 2 O 3-ZrO 2 coatings were deposited with solid lubricants, and their effects on the laser surface texturing (LST) under a lubricated condition (commercial engine oil, 5W30) were evaluated. All specimens showed a % dimple density, and the contact angle of the APS coatings after LST processing decreased by ∼19–50%.Cited by:

The NiCr–TiB 2 –ZrB 2 composite coating was deposited on the surface of blades made of steel (SUS) using high-energy ball milling technology and air plasma spraying technology, which aimed to relieve the wear of the blades during operation. The influence of titanium diboride (TiB 2) and zirconium diboride (ZrB 2) on the microstructure and wear resistance of the coatings was investigated. In this study, Mo-Cu-V-N composite coatings with high Cu content of ~18 at.% were deposited on L stainless steel and YT14 cemented carbide substrates by high power impulse magnetron sputtering in Ar–N2 gas mixtures. The influence of N2 partial pressure was investigated with respect to the microstructure and tribological properties of the by: 2.   A Systems Approach to the Solid Lubrication of Foil Air Bearings for Oil-Free Turbomachinery Christopher DellaCorte. The following paper introduces a systems approach in which the solid lubrication is provided by a combination of self lubricating shaft coatings coupled with various wear resistant and lubricating foil coatings. The use of Cited by:   Abstract. The growth of combustion processes along the years was driven both by scientific and technical developments providing disruptive innovations and by the market requirements)(e.g., the development of HVOF spraying by Browning in was pushed forward by the need to produce WC-Co cermet coatings with superior properties).Cited by: 1.
