RISMicrostructural Evolution and Tribological Performance of Laser-Cladded NiCrBSi/WC Composite Multilayer Coatings: Influence of Laser Energy Density and Powder Feed Rate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Unlike mono-layer claddings, the deposition of multilayer composite claddings involves fundamentally different and more complex thermal and metallurgical mechanisms due to cumulative heat input, altered interfacial ...
Temperature-Dependent Friction and Wear Properties of Laser Powder Bed Fused Maraging Steel 300: Impact of Direct Aging Post-Processing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This research explores the high-temperature tribological characteristics of laser powder bed fused (LPBF) maraging steel 300, with emphasis on how temperature and post-processing via direct aging impact its wear ...
Studies on Dry Sliding Wear Mechanisms of Al7075/Si3N4 Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this investigation, Al7075 aluminum alloy reinforced with Si3N4 particles (3, 6, 9, and 12 wt%) was used as reinforcements to manufacture composites through a stir-casting approach. The microstructural characteristics ...
