Document Type and Number:
WIPO Patent Application WO/2020/248644
Kind Code:
A1
Abstract:
Disclosed is a modification method of in situ dissolution on the surface of a metal material, comprising the following steps: (1) fully mixing a substrate metal and a modified metal powder to obtain a raw material powder; (2) preparing a metal material from the raw material powder obtained in step (1) by means of a preparation means under non-equilibrium conditions; and (3) heat-treating the metal material prepared in step (2) to bring same to an equilibrium state, and then cooling to room temperature, such that the doped phase is dissolved out onto the surface of the metal material, so as to obtain a modified metal material.
