Disclosed is a gear including a resettable metallic glass. The gear of the present disclosure includes, as a base material, a resettable metallic glass, wherein the resettable metallic glass includes at least one metal element selected from each of (a) the group consisting of Ti, Zr, and Hf and (b) the group consisting of Fe, Co, Ni, Cu, and Zn, and further includes at least one metal element to maximize the complexity in the thermodynamic enthalpy of mixing among constituent elements, thereby including multiple resetting cores in various atomic-scale cluster forms in an amorphous matrix, leading to a structure with maximized structural complexity.

Resettable gears and manufacturing method therefor

The present invention relates to an amorphous alloy having low frictional resistance and capable of improving abrasion resistance, a target made of the amorphous alloy, and a compressor comprising a layer of the amorphous alloy as a coating layer. According to the present invention, it is possible to secure high hardness and a low elastic modulus of the coating layer by controlling a microstructure having an amorphous phase as a primary phase by using Ti-based three-component to five-component amorphous alloys. As a result, it is possible to prevent the coating layer from being peeled off from a matrix or destroyed, and thus it is possible to achieve the effect of improving reliability or durability of a mechanical apparatus such as a compressor.
