Abstract
The present invention relates to a surface treating method for making an amorphous alloy component. The surface treatment method includes the following steps: an amorphous alloy sheet is provided; the amorphous alloy sheet is fixed into a dry blast machine; and the surface of the amorphous alloy sheet is treated by sandblasting. In the sandblasting step, air pressure is controlled to be in a range from about 1.5 gf/cm2 to 6.0 kgf/cm2 and blasting time is in a range from about 1 second to 60 seconds; the sand used in sandblasting is preferably selected from a group consisting of aluminium oxide, zirconium dioxide and silicon dioxide, and a grain size of the sand is in a range from about 100 μm to 250 μm.
