In recent years, the ultra-fine-grained materials are being actively developed and researched due to their unique physicochemical properties as compared with macrocrystalline (MC) materials.
Thus, it can be the ground to assume that diffusion coefficients and hydrogen accumulation capability in the volume of hydrogen-contained media for NC-materials will be considerably different from appropriate values for MC-materials.
Consequently, it may be supposed that materials in the NC-state can be perspective accumulators of hydrogen.

If the abrasive has sharp corner and the materials was cut.
If the abrasive corner is blunt the surface of the steels will produce many furrows and the abrasive will extrude the materials forward and push the materials move to two sides.

Introduction A lot of new materials with special functions have been developed continuously, such as composite materials, high melting point materials with high rigidity, ceramic materials etc, which can not be processed and formed with high efficiency and low cost by traditional machining.
It is benefit to spay the materials with a high melting point such as ceramic powders.
Reinforcing materials used for backing treatment often consist of epoxy resin, alloys with low melting point and resin-based composite materials containing metal powders.
