چکیده
121804-6565-IJMME-IJENS © August 2012 IJENS I J E N S Abstract— Finite journal bearing of elliptic bore and circular bush is analyzed considering the isotropic roughness in the bearing surfaces. The angle of inclination of the major axis of the sleeve to the load line and the attitude angle are kept constant while evaluating all the performance parameters. Film shape due to the rough elliptic bore is defined through the stochastic model of asperities distribution. The performance parameters such as load carrying capacity, friction force, flow into the bearing and side leakages are plotted and analyzed against the non-circularity for the various roughness parameters and eccentricity ratios.

Surface texturing is used to increase hydrodynamic pressure and reduce friction and wear between parallel sliding surfaces in a variety of applications. The shape, geometry, and density of the patterned microtexture features play a key role in the tribological performance of such textured slider bearings. Lubrication models are used to predict the load-carrying capacity, friction coefficient, a...

In this study, the effect of surface morphologies on the isothermal oxidation behavior of MCrAlY coatings fabricated by high-velocity oxyfuel (HVOF) processes was investigated. To do so, free standing coatings with as-sprayed and polished surfaces were isothermally oxidized at 1050°C. The thickness of the bond coat was approximately 380μm. The Ra of the as-sprayed and polished surfaces were 6.4...
