Abrégé

Disclosed are a GM type cryogenic refrigerator rotary valve and a preparation method therefor. The GM type cryogenic refrigerator rotary valve comprises an aluminum alloy rotating valve and an alumina ceramic membrane. A valve body of the aluminum alloy rotating valve is provided with a first surface for arranging a working boss and a second surface opposite to the first surface; and a high-pressure hole and a low-pressure groove are both provided in the working boss, and a vent hole is provided in the first surface; the high-pressure hole and the vent hole both penetrate the valve body, and an air chamber is formed on the second surface. The alumina ceramic membrane is plated on surface of the aluminum alloy rotating valve. The preparation method comprises: plating an alumina ceramic membrane on surface of an aluminum alloy rotating valve by means of a micro-arc oxidation process.

Abrégé

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.
