Detrimental effect of high-productivity L-PBF parameters on metal dusting resistance of Inconel 625
Source abstract
Abstract
The effect of increased productivity in L-PBF manufacturing on the metal dusting resistance of Inconel 625 wasstudied at 610 ◦C. Two sets of processing parameters were tested: the standard parameters given by the machinemanufacturer and degraded parameters with increased scan speed and hatching distance. The materials obtainedwith degraded parameters presented numerous lacks of fusion at the surface and exhibited significantly shorterincubation times before corrosion. Carburisation was preferentially localised around the defects where the oxidescale was less protective and where the confinement of the atmosphere could result in an increase of the localcarbon activity.
