Therefore, corrosion has become a key factor affecting the reliability and service life of tubing, and is the most important cause of tubing accidents [2].
Therefore, corrosion has become a key factor affecting the reliability and service life of tubing and is the most important cause of tubing accidents.
As an important metal material, titanium alloy has excellent physical and chemical properties and corrosion resistance.
The specimens was prepared by mechanical processing method, and the surface roughness was in accordance with GB/T 1031, the maximum allowable value of Ra is 3.2 μm.

An important factor affecting the level of interdiffusion is the cure temperature.
Cure temperature is known to affect the interdiffusion process since both the viscosity and gelation time, which influence the interphase thickness and morphology, depend on temperature [6,7].
The authors propose as future work the mechanical characterization of the interphase using nanoindentation and conducting further fractographic analysis with scanning electron microscopy.
Furthermore, studying residual stresses is considered to be also important to understand the underlying factors in the fracture behavior of hybrid composites.

Foam glass composite with good properties was prepared from iron ore tailings as the main raw material by two-steps method in this paper, the characteristics of which was determined by XRD and SEM technologies.
The crystal phase existing in the sample may improve the mechanical strength[5], but easily leads to generate more connection pores in the sample inside.

Table 3 shows the effects of various foaming temperature on the sample properties.
Besides, the holding time also has effects on the sample properties even at the same foaming temperature.

The noise of exhaust muffler is one of the key factors of the noise of the whole car.
The input side is at x = 0 and the output side is at x = L.Cascading property is the method that makes the four-pole formulation so useful.
Thus, clearly we found that the inlet temperature does not affect the transmission loss of muffler.

Previous studies indicated that [3-4] both the primary α-Al and eutectic silicon were significantly refined by the preparation process of semisolid technique, and the mechanical properties were also improved.
Tp is thought to affect the microstructure of semisolid alloy by cooling rate, undercooling and superheat and so on [4].
With the increase of Tp, the cooling rate and nucleation rate of melt are decreased but the crystalline size is increased, resulting in the morphology of microstructure and properties of the alloy are worse.

The characteristics of macro gather some structure and micro porous structure and the mechanical behavior and durability are connected closely.
Many researches show that pore structure characteristics strongly influence the impermeability, air tightness, frost resistance, corrosion resistance and other physical properties and the strength, stiffness and toughness and other mechanical behavior of concrete material.

Introduction Diamond films have excellent mechanical and tribological properties, such as high hardness and elastic modulus, good wear resistance, low friction coefficient and thermal conductivity, which make them the best candidates for wear resistant applications.
Since diamond is the hardest material known, conventional mechanical polishing methods are difficult to apply and very time consuming, especially for the complicated shape surface.
Moreover, the adhesion of the coating can be adversely affected since the processing temperature is generally high [1,2].
Moreover, NDFs have lower hardness than conventional diamond films because of the presence of amorphous carbon in the films, and contain a high level of intrinsic stress that directly affects their adhesion on WC-Co substrates.
As compared with the cemented carbide tools and drawing dies, the working lifetime of these diamond-coated tools and drawing dies increases by a factor of 5-10, according to practical cutting and drawing wire tests.

Thailand has been directly affected by climate change, and the volume of water in the main rivers of Thailand is subject to flash flooding; a common phenomenon.
(2) (3) Where f and are the friction factors in the pipe and the specific weight of the water, the friction factor (f) is the main data we wanted to observe.
With a decrease in the friction factor, the flow rate in the pipe increased.
The third theory presented by Sellin R.H. [2] explains that these polymers have an effect on the energy balance between turbulence production and dissipation due to the elastic properties of the macromolecules of the polymer solution which seem as spring to store energy before dissipation into the pipe wall.

Introduction Silicon carbide (SiC), particularly 4H-SiC, has in the recent years been in focus due to excellent electronic properties.
The change in volume at the sphere origin can be expressed as ( )33 3 4 hs rrv − =∆ π (2) This change of volume will affect the radius of the sphere of radius R.
Several techniques for calculating the critical thickness of an epilayer have earlier been presented [4,5] but these techniques have mostly been based on mechanical equilibrium of a grown-in threading dislocation that determines the onset of interfacial misfit dislocations.
The screw dislocation was chosen since it has lower energy density than the pure edge dislocation by a factor of 1/(1-ν) [6].
