One of the important reasons for choosing these materials is their ability to develop a naturally formed passive oxide layer, which is comprised of either amorphous or poorly crystallized non-stoichiometric TiO2 [5].
Wear modes [4] Materials and methods Cp-Ti II grade samples were grounded on SiC metallographic paper with different dimensions (from 180 to 1200).

The theory using the unified mechanical model, concise mathematical expressions, flexible and applicable to various features of material, its mathematical expression is: 　 　when (1a) when (1b) ,, as the material of the principal stress; as the material of tension and compression ratio; as the shear yield limit; as the compression of material yield limit; as the tensile yield limit of materials; Ductile metal materials Generally is 0.77 ~ 1.0, brittle metal material is 0.33 ~ 0.77, geotechnical materials Generally is less than 0.5, concrete is generally 0.065 ~ 0.100. b(0 ≤ b ≤1) is reflecting intermediate principal shear stress and normal stress on the material damage on the surface of the impact of material strength parameters.
Most metal materials have obvious yield point, and the tensile strength and compressive strength are equal.

Current bone graft materials are mainly produced from coralline hydroxyapatite (HAp).
Introduction Synthetically derived materials have been used as bone grafts in an attempt to overcome the limitations of autograft and allografts.
Materials and Methods Australia has rich variety of corals, however, their potential for use in implants has not been adequately investigated.
