Abstract
Described herein are embodiments directed to additive manufacturing (AM), including three-dimensional (3D) printing, of metal nitride ceramics. In some embodiments herein, AM may comprise powder bed fusion (PBF) techniques. Also described herein are metal nitride ceramic components formed by AM techniques and methods for forming metal nitrides capable of being used in AM processes.
Claims7
A process for producing a metal nitride ceramic component, the process comprising:
- preparing a metal nitride powder by contacting metal powder with a microwave plasma, the microwave plasma generated using a nitrogen-containing plasma gas;
- directing a laser beam or an electron beam to a powder consisting essentially of the metal nitride powder within a process chamber;
- and
- maintaining the process chamber at a temperature of 1,200° C. or less throughout the process.
