Because of the variety of metal materials, it's difficult to micro machine with one technique, especially machining those hard metal alloys.
It removes the rest material by electrochemical reaction, in which the material is dissolved at unit of single atom [4].
Because the electrode is very thin, the material of electrode should be of high stiffness.

The horizontal component paralleled to the surface of materials plays a dominant role when the incident angle of liquid is 30°, the morphology of scoured surface of materials is presented wavy folds, and there are more short-cutting marks at the same time.
The solid particles with high speed cut the surface of sample continuously, which made the materials loss constantly (Fig 2a).
Therefore, we should first consider the hardness of materials at the small incident angle, both consider plasticity of materials; in a large incident angle, priority should be given to the plasticity of materials, both the hardness of materials.

In general, inorganic geopolymers can be synthesized by alkali activation of materials rich in SiO2 and Al2O3 [9].
In this research, the raw materials used were combination of silica geothermal as silica source and kaolinite as alumina source.
The rate of reaction between alkaline liquid and source materials would increased by addition of sodium silicate to sodium hydroxide [3].
