Abstract

An additive manufacturing article according to the present invention is composed of an Ni-based alloy that contains Cr and Mo, while containing Ni in the largest amount in terms of the mass ratio; and an oxide film that is mainly composed of Cr is formed in a part or the entirety of the surface. This oxide film that is mainly composed of Cr has a region wherein the O content is higher in comparison to that in the inner part, and the Cr content is higher than the Ni content. It is preferable that this oxide film has a thickness of 1-20 nm from the surface; and it is also preferable that this oxide film is formed so as to be suited to a corrosive environment contact surface. In addition, this oxide film is able to be formed during additive manufacturing of the additive manufacturing article.
