RISA Preliminary Study on Hybrid Use of Thermal Spray Coating and Ultrasonic Nanocrystalline Surface Modification Technique on the Tribological Properties of Yttria Stabilized Zirconia Coating
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An ultrasonic nanocrystal surface modification (UNSM) technique was applied to a thermally sprayed yttriastabilized zirconia (YSZ) ceramic coating deposited onto a hot tool steel substrate to improve the mechanical and ...
Improvement in Microscratch Resistance of Graphite by Surface Modification for Molding Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the improvement in surface properties and microscratch resistance of graphites by means of an ultrasonic nanocrystalline surface modification (UNSM) technique. The surface roughness and surface hardness ...
A Study on the Effect of Laser Surface Texturing on Friction and Wear Behavior of Graphite Cast Iron
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dimples with various pitches and densities were produced using laser surface texturing (LST) to improve the friction and wear behavior of graphite cast iron. The objective of this study is to investigate the effectiveness ...
