Melt pool temperature modeling and control for Laser Metal Deposition processes [PDF]
2009 American Control Conference, 2009 Melt pool temperature is of great importance to deposition quality in Laser Metal Deposition processes. To control the melt pool temperature, an empirical process model describing the relation between the temperature and laser power, powder flow rate, and traverse speed is established and verified experimentally. A general tracking controller using the

Advanced Engineering Materials, EarlyView.Through direct application of porous transport layer (PTL) on the bipolar plate (BPP) with thermal spraying, the interfacial contact resistance is improved. With the cold gas sprayed BPP–PTL coating system, a proton exchange membrane water electrolysis cell with a cell voltage of Ucell = 1.9 V can be operated up to i = 2.5 A/cm2 in a dynamic mode ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.
