This paper focuses on investigating mechanical properties of micron-thick polycrystalline titanium nitride (TiN) films.
The research target is to evaluate elastic mechanical properties of micron-thick TiN films deposited by r.f. reactive magnetron sputtering.
The effect of Ar partial pressure during deposition on elastic mechanical properties of TiN films is discussed, and the properties obtained from XRD tensile tests are compared with those obtained from nano-indentation tests.
Elastic Mechanical Properties of TiN Films.
Therefore, better elastic mechanical properties of TiN films can be achieved by deposition with higher PAr.

At the same time the spectrum of traditional concepts based on regional factors are crystallized, including climate, landscape, building stone, functional and aesthetic priorities.
However, keep in mind two factors.
But all consolidates point design method, down in the final, combined with appropriate principles of Armenian building art, justified by local climatic, social, residential, structural factors.
High resistance to mechanical impact, its stone of sufficient strength and resistance, small volume weight, good thermal and other building properties are excellent indicators of the quality of the material.

Polymerization efficiency is one of the most important variable which affect the bulk materials properties [9].
However, in this study, we focus on the adhesive paste only in order to minimize factors and steps that can affect the elution.
One of the most important factors that affect elution is polymerization [10].
The polymer become softening and weakening the polymer network and resulted in leachable moieties and degrade the mechanical properties [31-32].

These properties along with good specific strength and modulus make them good candidate materials for many engineering situations where sliding contact is expected.
Experimental Thermoplastics exhibit superior properties such as enhanced toughness and prolonged shelf life.
Effects of control factors of the polymers are shown in Fig. 1 (a, b and c) for means SNR, respectively.
Among the control factors, the factor E showed the highest effect on the wear rate due to decreased elongation ability associated with self-lubricated property, followed by the factor S, respectively.

Description of material properties is a key factor in determining the coefficient of friction, coefficient of friction and speed.
Curves of the amount of wear at the same number of turn Taking into account we tested selected load (100N) is not high, it can be summarized to this test of speed on the friction properties of rubber as follows : constant in the low load conditions , the dry friction CR/EPDM blends - steel with the friction coefficient increases with the speed in a range of fluctuations .
The impact of temperature on the friction performance of CR/EPDM blended Sliding process, the working conditions (load and speed), friction and wear is often due to temperature rise caused a lot of material mechanical properties (elastic modulus and hardness), and lubricating properties as the interface temperature rise degradation, thus affecting their tribological behavior [9].
Loads must change the speed of the test , with increasing speed , the test conditions of rapid temperature rise would have an impact , when the speed exceeds 300r/min has been difficult to clearly observed in the friction coefficient increased with the speed of growth ; A certain speed , to change the load test , when the load is low , the impact of load variation on the friction coefficient significantly in the temperature on the friction coefficient , when the load increases to a certain value , the change of load on the friction coefficient is weakened the temperature change has become a major factor influencing the fluctuations in the friction coefficient , but the determinants of the coefficient of friction , the material properties.

The relation between oscillation frequency and volume flow rate only shows a weak function of fluid properties and temperature.
This kind of micro whistle could be employed as gas flow sensor which is insensitive to fluid properties.
It is also interesting to check whether the organ pipe micro whistles produce the same frequencies for gases with different properties.
The amplitude measured is amplified by a factor of 180.
The characteristic curves of organ pipes appear to be only a weak function of fluid properties such as density and temperature.

Deposition rate change tendency schematic of the thin film of 1Cr18Ni9Ti The influence factors of thin film deposition rate are various.
Surface appearance of the thin film of 1Cr18Ni9Ti 15,000× Because 1Cr18Ni9Ti stainless steel is a kind of alloy material, the consistency of the composition between the film and the target is an important factor that affects the property of the film.
There are multiple factors of sputtering technology parameters can affect the adhesion between films and substrates.
Film adhesion is affected by the multiple factors of Van der Waals force, diffusion, mechanical lock, electrostatic attraction and chemical synthesis influence.
From the above analysis, it can be seen that the film adhesion is affected by the multiple factors of sputtering time, sputtering power density and target materials.

The solid model of the tracking mechanism, which contains the mass and inertia properties, was developed in the CAD environment SolidWorks, and then it was imported in ADAMS through the PARASOLID file format (via ADAMS/Exchange interface).
The values domains, where the factors vary in the optimization process, have been established likewise: [1, 104] - for the proportional factors, respectively [0, 103] - for the derivative and integral factors.
The investigation strategy used to create the design matrix is based on the DOE Screening technique [16], which allows identifying the factors and combinations of factors that most affect the behavior of the system.
The idea is to consider every factor that may potentially affect the response, and use a screening analysis to determine how much each contributes to the response.
Due to the relatively high number of factors included in the optimization process (concretely, 6 factors), it was chosen the Plackett-Burman technique, with eight inputs in the design matrix (the minimum necessary of combinations).
