The properties of the final SLM components depend on the process parameter optimization.
Based on the literature data [8-15], it can be concluded that thanks to elaboration of surface modification by PVD (Physical Vapour Deposition) of pure titanium it will be possible to produce functional implants, which mechanical, physicochemical, and electrochemical properties affect the limitation of factors causing progressive destruction processes in the human body [15-23].
Pure titanium is characterized by high biocompatibility and corrosion resistance, and of course satisfactory mechanical properties, which makes it a good material for cooperation with the bone.
In order to eliminate unfavorable factors, it is necessary to use surface modification.

This article takes lwb350 horizontal spiral sedimentation centrifuge for example, with the help of FLUENT software, the relationship among the separation efficiency and the working speed as well as feed flow is analyzed through the numerical simulation of solid-liquid separation, which can provide reference for the application of simulation analysis and research on properties of spiral centrifuge.
The numerical simulation and analysis of separation characteristics of lwb350 type horizontal spiral sedimentation centrifuge Variable factors affecting the separation efficiency.
For horizontal spiral sedimentation centrifuge, variable factors affecting the separation efficiency are the adjusted operating parameters according to the actual working condition, which include separation factor and flow and so on.
Therefore, taking all factors into account, the reasonable condition speed of lwb350 horizontal spiral discharge sedimentation centrifuge is 2600 r/min.

The microstructures and the mechanical properties of the severely plastic deformed materials are closely related to the degree of plastic deformation, hence, understanding the phenomena associated with the stress, strain and strain rate development is very important for an optimum ECAP process design and the best final mechanical properties.
Figure 1 shows (a) a schematic drawing of ECAP, showing various geometric factors which are considered as the major controlling factors (i.e. channel and corner angles) for strain and microstructural evolutions and (b) an ECAP processing die set.
Although the two angles, channel angle and outer corner angle, are easily controllable factors, there are many other control factors in geometry, material and processing variables listed in Table 1.
The control variables affect internal parameters, resulting in success or failure in terms of geometries and properties of the ECAP processed workpiece.
For this purpose, the finite element results of ECAP for various geometric factors are described.

Bamboo is well known as the oldest structural material that posses unique anatomical structure and superior mechanical properties.
Structural applications pay more attention on safety, durability and mechanical properties.
Density also was carried out as the factor that affects the compressive strength of round bamboo.
The mechanical properties of bamboo depend on the orientation and concentration of vascular bundles.

HPTE is a modern mechanical nanostructuring technique that can refine the microstructural properties and subsequently affects the mechanical and functional properties of the materials.
The adsorption process is reversible, and the amount of adsorbed hydrogen depends on factors such as temperature and pressure.
There is a constant drive to develop novel processing techniques that can enhance the mechanical properties and performance of materials.

A Comparison of the Mechanical Properties of RF- and DC- sputter-deposited Cr Thin Films Minwoo Parka,d , Wangwoo Lee a , J.
Effects of DC or RF sputtering power on the deposition rate and properties such as hardness and surface roughness of the Cr films were investigated.
Results and Discussion The important factors in developing a sputtering technique as an alternative to electroplating are to increase deposition rate.
Hence, it should be a good strategy to increase the upper limit of the sputtering power to as high as possible when assembling a sputtering system and to use a power as high as possible within the hardware limit of the sputtering system when depositing a Cr film without harming the physical and mechanical properties of the film such as hardness, surface roughness and corrosion-resistance.
According to Paturaud et al's report[7], the hardness of the Cr film is proportional to the film deposition rate and the most important process parameter affecting the deposition rate is sputtering power.

In order to give full play to CaCO3 whisker’s novel micro structure, excellent mechanical properties and stability, we initially applies it to advanced cement based construction materials.
Since its low cost, the mechanical properties of the composites could be greatly improved by addition of CaCO3 whisker, without increasing costs.
Li Lixia et al, [4] using soluble phosphate as control agent, prepared calcium carbonate whisker with good crystallinity and high content of aragonite phase by gas-liquid carbonation method, and further studied the factors affecting the product quality, such as amount of the soluble phosphate, carbonation temperature, inflation speed of CO2 and initial mass fraction of Ca(OH)2 slurry.
The two factors are considered as the most important factors of the crystallization of selective inducing aragonite whisker.
In our early research work, the microstructure and effect of different whiskers content on the mechanical properties of PC were investigated, which were show in Figure 8 and Table 1, respectively.

These properties depend, not only on composition and size of the used powder, but are strongly affected by process parameters and manufacturing strategy.
Factors for this model are discrete variables, therefore the ANOVA examines whether the variance of the factor is zero.
It is quite evident that both the two input factors P and v affect output factors; in fact the p-value is always lower than α.
This is due to the increasing of the density of built parts, that generates better mechanical properties.

Introduction Fibrous materials produced from collagen have poor properties such as mechanical capacity,thermal stability,water resistant and degradative time fixation etc.
Properties such as mechanical,water-resistant and heat stable etc were improved most.
The key factor affecting property of blending system is the mass ratio But the effect of blending temperature and time were little.
