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/cmto 6.0 kgf/cmand 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 &#x3bc;m to 250 &#x3bc;m.

Amorphous alloy component and surface treating method for making same

A method of cutting bulk amorphous alloy includes: positioning a target cutting path of the bulk amorphous alloy in an atmosphere of an inert gas; cutting the target cutting path to form a cut surface using a pulsed laser; and removing a plurality of burrs located on the cut surface produced during the cut.

Method of cutting bulk amorphous alloy

A method of surface grinding a Zr-rich bulk amorphous alloy article includes providing a substrate; providing a first surface grinder for rough surface grinding; and providing a second surface grinder for finish surface grinding. During the rough surface grinding, the rotating speed is in the range from 20 r/min to 30 r/min, the grinding time period is from 3 minutes to 12 minutes, and the grinding pressure is from 1 kg/cm2 to 2 kg/cm2, and a first pump circularly conveys a first lubricant to a first rotating abrasive wheel. During the finish surface grinding, the rotating speed is in the range from 30 r/min to 40 r/min, the grinding time period is from 5 minutes to 7 minutes, and the grinding pressure is from 1 kg/cmto 2 kg/cm, and a second pump circularly conveys a second lubricant to a second rotating abrasive wheel.
