Additive Layer Manufacturing using Metal Deposition

Abstract

Among the additive layer manufacturing techniques for metals, those involving metal deposition, including laser cladding/Direct Energy Deposition (DED, with powder feeding) or Wire and Arc Additive Manufacturing (WAAM, with wire feeding), exhibit several attractive features [...]

Effect of Laser Cladding Stellite 6-Cr3C2-WS2 Self-Lubricating Composite Coating on Wear Resistance and Microstructure of H13

“…Adding alloy powder with the similar chemical composition into the base material can ensure an excellent metallurgical bonding interface. As a competitive and effective surface strengthening technique, laser cladding can produce microstructure with fine and even crystals, thereby the mechanical properties of the coating are improved [9][10][11][12][13]. Compared with the traditional technology of improving surface properties, the laser cladding exhibits many outstanding advantages, such as concentrated heat input, short processing time, fast coating cooling, low dilution ratio of the cladding layer, good metallurgical combination of substrate and cladding coatings, wide selective range of laser cladding powder, and so on [14][15][16][17].…”

Hydraulic transport regimes of grains in a millifluidic confinement

“…Transporting granular material is essential for a large range of industrial activities working from granulated raw material. From powder handling in selective laser sintering additive manufacturing [1], factory processes requiring continuous supply with a powder, to the extraction of drill cuttings from a well [2], conveying grains techniques cover very different scales. Fluidization systems such as pneumatic or hydraulic conveying represent scientifically challenging problems due to the complex interaction between the suspending fluid phase and the granular phase [3].…”
