RISHigh-Temperature Tribological Performance of Additively Manufactured Inconel 718/Al2O3 Metal Matrix Composite Coatings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The wear mechanisms of an additively manufactured Inconel 718/Al2O3 metal matrix composite (MMC) coating under both the ambient and high temperatures are investigated. First, a powder-fed laser-directed energy ...
Hybrid Analytical-Numerical Modeling of Surface Geometry Evolution and Deposition Integrity in a Multi-Track Laser-Directed Energy Deposition Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modeling multitrack laser-directed energy deposition (LDED) is different from single-track deposition. There is a temporal variation in the deposition geometry and integrity in a multitrack deposition, which is not well ...
