Abstract
Electrolytic medium for electropolishing and electropolishing method using the electrolytic medium. The electrolytic medium includes solid particles retaining therein a water. Covering each of the solid particles that retains the water is an electrically non-conductive immiscible liquid. The non-conductive immiscible liquid is displaceable on the solid particles to allow electrical conductivity between solid particles that contact one another and to allow electrical conductivity between the solid particles and the workpiece upon the solid particles contacting the surface of the workpiece.
Claims20
An electrolytic medium for electropolishing a workpiece made of a conductive inorganic composite material, the electrolytic medium comprising:
- solid particles that each retains a liquid comprising distilled water;
- and
- an electrically non-conductive immiscible liquid covering each of the solid particles in which is retained the distilled water, the electrically non-conductive immiscible liquid being displaceable on the solid particles to allow electrical conductivity between solid particles that contact one another and to allow electrical conductivity between the solid particles and the workpiece upon the solid particles contacting a surface of the workpiece.
A method for electropolishing a surface of a workpiece made of a conductive inorganic composite material, the method comprising:
- contacting the surface of the workpiece against an electrolytic medium that comprises solid particles that each has retained therein a liquid comprising distilled water, each of the solid particles retaining the liquid being covered by an electrically non-conductive immiscible liquid;
- electrically connecting the workpiece to a first pole of an electrical power supply and electrically connecting the electrolytic medium to a second pole of the power supply, the first and second poles having opposite polarity;
- and
- producing relative movement between the surface of the workpiece and the solid particles of the electrolytic medium.
