Study of mechanical polishing of CVD diamond thick films;

Development of the Rotator Special for Autoclave Body Polish;

The Design of a Self-oscillating Abrasive Water Jet Polisher of Economy Type;

The design of the grinding liquid pulse shot flow polisher;

Ultrasonic is applied in slider lapping.

The thickness of the slurry film in one lapping process with a kind of texturing plate surface was calculated as an example.

It is a contradiction to achieve a high material removal rate and a super smooth surface in lapping of magnetic head.

Development and expectation of laser polishing technology;

The principle and affecting factors of laser polishing of diamond films are disc ussed.

Several factors affect the material removal rate of laser polishing process and polished surface roughness, such as laser energy density, wavelength, pulse width, incidente angle, scanning speed and scanning way of laser beam, material properties and structure and so on.

After treated the surface of NiNb2O6 photoelectrode by mechanical polishing +chemical etching + photoetching, the stable values of the differential capacitance of the spacecharge layer are measured,the relationship between flatband potential Vfb and pH value of the electrolyte is obtained,and the value of Vfb is compared with its theoretical calculating value.

The affections of different surface treatments by mechanical polishing, chemical etching and photoetching to the properties of electrodes have also been discussed.
