From here, obvious furrows can be found and they are caused by the chip materials of the hard phase materials.
Also, as the grains of the structure are bulky and they are not easy to fall from the materials, there are not many pits on the wearing surface.
As the grains are small, the furrows caused by the peeled hard phase on the materials are narrow and numerous.

In addition to the development of new materials, the promotion of existing material properties is one of the important research direction, such as the application of Severe Plastic Deformation(SPD) refinement material organization, can make the material with higher strength, while retaining toughness with ductility [1].
Rotating Compression Forming method applying compression and rotation at the same time can also control the material structure [2], the properties of the material will be extended in a specific direction into a continuous gradient of the product, the product can be applied on the material which outside needs high hardness, and the internal needs of a certain toughness of the product, such as biodegradable magnesium alloy implant [3].
