The materials synthesis can be divided into the following several steps: material selection → regent purification → mixing material → grinding → compression moulding → sintering.
After 12 h, the materials are taken out and then put into agate mortar for grinding.
First, when temperature is close to melting temperature of material, in cases of skillfully mastering procedures of materials melting we should increase temperature as fast as possible to make all the materials melting in a relatively short period of time, in order to avoid appear in the process of climbing.

Introduction The human bones are the organic/inorganic composite materials, which is composed of hydroxyapatite (HAP) and protein with nanometer sizes.
Poor mechanical properties of pure HAP materials such as the lower strength and tenacity would lead to the problems of loosening, transferring and fracture for the materials implanted in vivo [1,2].

At present, flux-cored wire composite material, nano material and new alloy material be used as spraying materials.
It is difficult to made solid-cored wire with above materials.
Some insulating materials possessing special chemical elements only be used in coating as flux-cored wire.

The increase in wear rate takes place for both micro and nanocrystalline materials.
However for microcrystalline materials it is higher for all loads than the nanocrystalline coatings.
However, these traditional materials can result in a coating that is subject to spalling under elevated loads or component cycling (fatigue). 500 µm a 100 µm a 500 µm b Fig. 4.
