Influences of different surface treatments on titanium substrate to HA/TiO2 bioactive coatings Shengjiang Wu, Huiping Shaoa and Ran Wei School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing 100083, China aemail: shaohp@ustb.edu.cn Keywords: hydroxyapatite; titanium alloy; electrophoretic deposition; composite coating Abstract.
Porous structure of the organization is not only beneficial to cell adhesion, but also play an important role in mechanical properties, and they can meet the requirements of implanted materials [2].
Titanium alloy surface coated with HA has good biological activity, and makes the implanted materials with excellent mechanics performances of titanium and favorable biological properties of HA ceramic, which has become one of hot topics in biomedical materials research currently [3].

Recycling Automotive Parts and Components Model Recycling is a car spare parts and materials available according to the nature of the classification of parts and components to achieve reuse or recycling of materials; Regeneration is a new product in the use of used or obsolete parts and components and materials [2] Reference foreign auto recycling experience, Combined with the actual situation in China, through the dismantling of waste motor vehicle recycling process research, the authors put forward the resources the used car model of the process of recovery, as shown in Fig.1.
Recycling vehicles including parts and materials re-use the re-use; it should be mainly at the design stage to consider two aspects of this design strategy.
Fig.3 the disassembly of the design criteria for the design (2) Guidelines to reduce the types of materials.

Working above limit temperature for long-term, metal materials of exhaust valve are likely to anneal, which leads to the great reduction in hardness of the valve materials, enlargement in deformation and wear of valve, and even to fracture.
The 21-4NWNb is chosen for the material of valve head, while 40Cr as material of the valve rod.
The property of two kinds of materials are as follows: the modulus of elasticity of the bar and the head are () and (), so as their poisson's ratios 0.277 and 0.3, their densities () and (), their coefficients of thermal expansions () and(), their specific heats ()and (), thermal conductivities 44.0 () and 14.5 ().
