Additive manufacturing method for manufacturing a metal part comprising inclusions of at least one phosphor compound

Abstract

A method for manufacturing a metal alloy part by additive manufacturing, the metal alloy comprising a metal element A and the part further comprising inclusions of a phosphor compound consisting of a metal oxide doped by said metal element A. The method includes forming a layer comprising said metal alloy comprising a metal element A and inclusions of said phosphor compound by an additive manufacturing technique selected from laser metal deposition and laser powder bed fusion, from a mixture comprising a metal alloy powder comprising the metal element A and a precursor powder of said phosphor compound. The precursor powder consists of a powder of the metal oxide optionally doped with a metal element B different from the metal element A, said phosphor compound being formed in situ, during the implementation of the additive manufacturing technique, by atomic diffusion of a portion of the metal element A of the metal alloy to the metal oxide and exchange of the metal element A with a metal element of the metal oxide.
