Abstract
A method of manufacturing an object by joining a first component and a second component. The first component comprises metal powder with a first alloy composition and a first soluble binder, and the second component comprises metal powder with a second alloy composition and a second soluble binder. They may further comprise ceramic powder. At least one of the surfaces to be joined is dissolved before they are brought in contact, or a mixture of metal powder with a third alloy composition and a dissolved third binder is arranged there between. The chemical differences between the first, second, and third alloy compositions are within predetermined limits. The components are sintered or oxidized together whereby it is possible to obtain an object wherein the transitions between the material phases from the joined components are close to inconspicuous when analysed with scanning electron microscopy.
