The choice of material for the low pressure turbine blades and the high pressure compressor blades is one key factor to decrease the weight of the engine.
Gamma-TiAl materials are suitable for applications in aircraft engines because of their good oxidation resistance at temperatures up to 700 degrees Celsius in combination with excellent mechanical properties [2].
The main advantages of the laser cladding process are high precision, a minimized heat affected zone (HAZ), low distortion and the variety of materials.

Introduction Commercially available pure titanium has been frequently used as dental and orthopaedic implant material because of its suitable mechanical properties, significantly lower density, excellent biocompatibility and superior corrosion resistance which are required in biological environments [1-3].
Corrosion behaviour of metallic biomaterials is one factor used to determine material degradation and biocompatibility.
Proteins affect the corrosion behaviour of implanted materials and either increase or decrease corrosion [10,11].

IMC in solder joints serve mechanical strength and electrical conductivity for electronic parts [1].
When the thickness of IMC is very thick, the joint of solder and electronic parts become brittle and will affect the reliability and performance of the solder [3,4].
However, aging temperature has been the most influence factor for IMC growth compared to aging time.

The dynamics of the rotary control valve is described by the following system of equations: (1) where m – weight of the rotary dispenser 2 with crank 6; Vcx – the speed of the crank 6 in the projection of the x-axis; xc – the movement of the crank 6 on the x-axis; α – the coefficient characterizing losses of the rotary control valve; Fout – the force formed by the pressure in the cylinders 4 or 5 (Fig.2), which pushes the crank 6 and depends on the position of the piston-striker (outer factor); Fx – the force acting through the roller 8 in the projection on the x-axis.
Therefore, we can affect the operation of the valve, and thus to the work of PHIU by changing the design parameters (the radius of the rounding of the crank 6 and the radius of the roller 8) and the pressure in cylinder cavity 7.

Following factors are the bottom line: · weight of OM; · dynamic property of handling equipment (robot, manipulator); · terms of suction cups loading balance; · size condition and decomposition of mass of OM; · size and layout of suitable areas for gripping of suction cup; · surface characteristics of OM.
Moreover, the higher quality of vacuum that should be reached by ejector, the higher the demands on the power supply of energy (compressed air), Fig. 2 Gripping force of the suction cup is proportionally affected by its size, Fig. 3, which is useful almost without any limits.
When calculating the real force by relations (1), respectively (2) the theoretical force must be multiplied by , where t refers to as safety factor.
Equation for the calculation of real grip force so takes the form [N] (4) wherein safety factor t is determined depending on the orientation of the active handling acceleration.

Here, shear correction factors are required to obtain the relationship between the resultant shear forces and the shear strains.
An anisotropic material is a material that has its elastic properties vary in different planes.
These elastic properties are the elastic modulus, Poisson ratio and the shear modulus.
Whereas an isotropic material has the material properties being the same in all directions.
Example Problem The engineering properties of unidirectional graphite/epoxy material are given by [18] as shown below.

Appropriate choices of material properties are necessary to have an accurate simulation of the reinforcement system in numerical modelling.
As listed in Table 1, the properties of the embankment, soft clay and stone columns were obtained from the published work of Alkhorshid et al. [34].
The dimensions and properties of the locally weak zone (Sabkha soil) were chosen to match values stated by Benmebarek et al. [31] as B = 0.6 m and DEP = 3 m respectively width and depth of the LWZ as shown schematically in Fig. 2.

These processes involve high deposition temperatures that restring the use on substrates that can not be exposed to high temperature without degradation of the mechanical properties.
It is reasonable to think that Zr additions only affect the precursors generation, leading to the partial pressures of the Al-chlorides change drastically and favouring the aluminium deposition. 01234567891011 0 10 20 30 40 50 60 70 80 Chromium Aluminium Iron % Atómic Distance from the surface (μm) Fig. 4.
Table II Energy of activation and frequency factor.
The activation energy for single Al deposition and Al/4%wtZr deposition is 122.9 and 125.8 kJ mol-1 respectively, which are practically the same, since in both cases the deposition kinetics are controlled by the same factors.
The increasing in the deposition rate in case of the Al/Zr deposition system is related with the higher frequency factor in this deposition system.

Wall thickness is the main factor that affects paper pulp molding products intensity.
Excessive arc radius is decided by product, paper property and packing special requirements, normally 2~5 mm.

Dislocations are the most significant of the defects in the crystal structure, which have a significant effect on the mechanical and electrophysical properties of semiconductors (conductivity, luminescence, strength), the kinetics of phase and structural transformations, and diffusion processes [4].
Also the current affects in the picture of the linear defects distribution near the stress concentrator, as illustrated in Fig. 5.
The main factor influencing these processes is revealed.
