Properties of micro-arc oxidation ceramic film are conditioned by many factors, including electrolyte composition and its ratio, electrolyte PH value, the power supply parameters settings, etc. [4-5].
By Fig. 2 micro-arc oxide film surface morphology: many uniform size and shape similar volcanic eruption shaped holes are distributed on the film surface evenly; the film is composed of the density ntima and loose outer film, which is very conducive to the growth of osteoblast adhesion and bone tissue in a clinically context and improve mechanical binding between implants and biological bone.
Section structure and chemical composition-thickness.Cross-section morphology of micro-arc oxidation ceramic film obtained under different voltages is shown in Fig. 3 .It can be seen from Fig. 3, oxidation voltage affect the porous film thickness.

Similarly, there are some factors that can not be theoretically modeled in the EDM process of PCD.
are the factors.
The three factors and four levels of each factors are shown in Table 1.
Fig. 3 shows the graphs of MRR and Ra that use the control variable method to change one of the factors and keep the other two factors respectively.
In order to reflect the relationship between factors more fully, these three factors are further studied by experiments.

Optical properties of the touchscreen were assessed using a spectrophotometer to measure the transmitted light over the range of visible wavelengths.
Both the force-resistance profiles and the optical properties of the layer are dependent on the granule loading and composition.
The force-resistance profile and the optical properties of the resulting touchscreen can be controlled by the size and composition of the functional granules in the composite ink.
The optical properties of the ITO/glass substrate and force sensing layer were determined using a spectrophotometer to measure both total transmission and diffuse transmission (haze).
Upon Table 1: Ink compositions and optical properties.

Introduction Refractory metals such as V, Nb and Ta are coated with Pd to constitute a composite membrane for hydrogen separation since these metals easily form oxide layers, and the surface reaction affects hydrogen transport [1,2].
Various mechanical and chemical techniques are used to achieve this aim.
Further work is required to evaluate its mechanical properties such as toughness and fracture strength. 30 40 50 60 70 80 90 100 110 120 2θθθθ (degree) Intensity (a.u) BCC V(!
The origin of the internal stress as a factor leading to crack formation is key to understanding hydrogen embrittlement.

A continuous chip formed and improvement of the tool life in turning operation are important factors to prevent the attainment of machining automation.
Friction between the tool and a chip affect the feed force.　
It is considered that lubricating property between the tool and the chip improved by the high-pressure coolant supply.

How does immersion time in NaOH solution influence the structural and electrochemical properties of the activated carbon?
Moreover, can OPEFB-activated carbon demonstrate sufficient electrical properties to be considered a viable material for battery electrodes?
Many factors can influence this fluctuating phenomenon of generated voltage.
This is influenced by many factors such as the use of activators, anode and cathode materials and the type of biomass used, moreover during the manufacturing process, each method will also affect the results obtained.

Unfavourable influence of coarse-grain microstructure and favourable influence of its refinement on a number of mechanical properties place the problem of finding solutions for the effective grain refinement in the circle of fundamental issues for this group of alloys [9÷11].
Taking these factors into consideration, it seems appropriate to become interested in heat treatment procedures as alternative methods for grain refinement of TiAl intermetallic alloys.
The result is improvement in strength properties of alloys subject to heat treatment.
The grain refinement of TiAl intermetallic alloy by applying cyclic heat treatment is an efficient method for improvement in mechanical and plastic properties as well as hardness of alloys.
The application of under-annealing after cyclic heat treatment results in further increase in plastic properties.

In Fig.3 (b), it could be observed that the hardnesses of the complete plates’ core layer were largely affected by heat treatment.
Since ordered phase was the main factor leading to the sharply increasing of material’s hardness and brittleness, restraining the formation of ordered phase or decreasing the material’s ordered degree could reduce the material’s hardness [9].
These factors resulted to the decreasing of the hardness of composite plate compared with the hot rolled ones.

Brinson has modified the constitutive equation of Tanaka by introducing the dependence of transformation strain on the single internal variable component xS and the dependence of the elastic properties on the total martensite fraction, i.e., xS + xT.
In the construction of the kinetic relations the following functions of alternating-sign stress s and temperature T will be used: (20) where the factors are bound to the kinetic parameters by the following equations: ; ; ; ; . (21) The functions in Eq. 20 denote the linear combinations for the current loading components s, T.
