Many materials with different surfaces have been developed for dental and orthopedics implants.
When these materials are inserted into bone several biological reactions occur.
However, due to the passivation property of titanium, the healing process is slower than the other implant materials with bioactive properties such as calcium phosphates [11], furthermore the fixation of the implant is weaker when compared to calcium phosphate (CaP) materials [12].
Materials and Methods The Ti-7.5Mo alloy was produces from sheets of commercially pure titanium (99.9%) and molybdenum (99.9%).

While the economy is under continuous development, people’s life quality will be improved to certain degree; under this condition, people will have higher and higher material requirement.
Under the market economic system, both emerging industrial structure and transformed industrial structure shall be established on the basis of science and technology; the workers shall firstly get hold of advanced production knowledge and technology, and then they can apply the change of industrial structure.

Abstract
SEM observations and Vickers-hardness tests were performed to identify the irradiation effects. γirradiation effect during the aging hardening
process can be explained depending on the
composition of the alloy and is used to derive quantitative information on the kinetics of the
transformation precipitates.
γ-irradiation probably play the key role in defects responsible for material strengthening and embrittlement.
Therefore, γ-irradiation probably play the key role in defects responsible for material strengthening and embrittlement.

Introduction
Slot coating adheres one layer or multi-layer thin and functional materials to the surface of a body, replacing the air of the substrate’s surface, to protect, decorate, and apply functions to a substrate.
The rheological properties of coating materials cover a wide range, making it difficult to grasp the optimum condition for successful coating.
The material used in this study is Ultraviolet Cure Adhesive(UV adhesive).
According to our results, the material viscosity used in this study as shear-thinning materials decreases with an increasing shear rate.
