Method of covering substrate surface with sintered layer and powdery raw material used for the method

摘要

A method of covering a substrate surface with a sintered layer comprises the step of loading a powdery raw material in a region of forming a sintered layer on the surface of a substrate, and the step of sintering the loaded powdery raw material so as to form a sintered layer on the surface of the substrate. The powdery raw material contains at least two elements and has a temperature region in which a solid phase and a liquid phase are present together. The liquid phase is wettable with the substrate. The sintering step is performed within a temperature region in which the solid phase and the liquid phase of the powdery raw material are present together.
