RISTribological Performances of Modified Babbitt Alloy Under Different Sliding Modes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper aims to improve wear resistance of bare Babbitt modified by CuLa and evaluates the effect of different sliding modes on tribological properties of bare Babbitt, Babbitt modified by 0.5 wt% CuLa (marked by ...
Two-Dimensional Simulation of the Collapse of Vapor Bubbles Near a Wall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to investigate the erosion extent and mode of cavitation in different states by the commercial code FLUENT and evaluate the reliability of the software, the collapse processes of a ...
Synergistic Lubricating Performance of h-BN/GF Nanoparticles as Oil Additives for Steel-Steel Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The major objective of this work is to investigate the synergistic lubricating performance of hexagonal boron nitride (h-BN) and graphite fluoride (GF) nanoparticles (NPs) in white oil. The tribological tests were carried ...
An In Situ Fabrication of CuGa2 Film on Copper Surface With Improved Tribological Properties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Interface interaction between gallium-based liquid metal and copper-based materials results in the formation of intermetallic CuGa2 grains. In particular, CuGa2 grains are able to produce a uniform film and the newly formed ...
A Design of Coverage Area for Textured Surface of Sliding Journal Bearing Based on Genetic Algorithm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper aims to improve the tribological performance of journal bearings by optimizing the coverage area of circular microtextures in divergent region of the sleeve. A numerical model is proposed to calculate the friction ...
Simplified Calculation of Recess Pressure Considering the Hydrodynamic Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hydrostatic journal bearing’s recess pressure is to be determined using a novel approach. This method treats the circumferential bearing lands on both sides of recesses as infinitely long bearings, and the axial bearing ...
Laser Com-Texture on Ti6Al4V Surface for Lubricant Transportation to Improve Tribological Properties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Artificial joint materials often wear out due to poor lubrication, affecting their service life. A compound texture (com-texture) was prepared, to improve the spreading of lubricant at the friction interface and reduce the ...
Synergistic Lubrication for Textured Surfaces Using Polar and Nonpolar Lubricants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The synergistic effect of surface texturing and lubricants with various viscosity and polarity properties is an attractive and unexplored topic. In this study, surface texturing characterized by circular dimples has been ...
Study on the Surface Texture-Microparticles Synergistic Lubrication Mechanism of Artificial Joint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: After total joint replacement surgery, frequent injection of lubricating substances is required due to lubrication failure caused by the absorption of lubricants by the human body, which will cause serious physiological ...
