Without the polarization, the composites will have no piezoelectric properties.
Results and discussion Influence of poling temperature on the piezoelectric properties.
So the piezoelectric properties of the piezoelectric composites are also improved.
The relationship of electromechanical coupling coefficient, mechanical quality factor and the acoustic impedance with the poling temperature are shown in Table 1 and Table 2.
The planar electromechanical coupling factor Kp, thickness electromechanical coupling factor Kt, mechanical quality factor Qm and acoustic impedance Z of the composites change little with different poling temperature.

The physical properties of dental composite, such as Diametral Tensile Strength (DTS) and hardness could be affected by the filler of the composite.
Zircon emerged as an alternative because it has better physical and mechanical properties than the silica-based filler which easily found in Indonesia.
Zircon sand has better physical and mechanical properties than silica.
Both of these factors can be controlled by regulating the concentration of MPTS [8].
The other factors that may affect the silanization process of MPTS are the amount of water and the pH of the solvent.

In order to investigate the mechanical behavior of the DM joint and more accurately incorporate its mechanical properties, several FEM models have been developed from 3D models [17-20].
Material Properties The material properties adopted were specified in terms of Young's modulus and Poisson's ratio for the implants and all associated components.
The interaction between two factors, d and mc/i is depicted in Figure 9b.

Because there exists a functional electrolyte, this affects the surface quality of workpiece machined.
In general, the surface integrity consists of the superficially geometrical characteristic, physical and chemical property.
The physical and chemical property includes the surface hardness, residual stress, strength, structure ingredient and so on.
Fig.3 The effect of the medium and the cutting passes on the hardness of the samples Orthogonal Experiment Besides the medium and cutting passes, there are still other factors that can affect the surface integrity in WEDM-HS.
In the experiment, medium, cutting passes, working current and pulse duration serve as four factors, each factor containing three levels (see Table 3).

Very significant feature of spinning is ability to produce components with high mechanical properties and high quality of surface layers.
Very significant feature of spinning is ability to produce components with high mechanical properties and smooth surface finish [3, 4].
These factors define the surface integrity of component and have direct impact on service life.
In order to assure the statistical properties the runs were made in randomised order.
Metal spun and deep drawn part´s surface layers properties evaluation.

The results showed that the surface roughness strongly affected the properties of the superplastically carburized duplex stainless steel while its effects on the non-superplastic material were not that obvious.
Introduction Carburizing is a surface treatment process, to improve surface properties of engineering components.
From this study, we can conclude that the effect of initial surface roughness is important to carburizing properties.
The combination of the two factors eventually leads to better carburizing properties.
The surface roughness of superplastic DSS affects the surface properties of the superplastically carburized specimen where smoother surfaces increased carbide layer thickness and surface hardness.

Aluminum alloy heat treatment parameters are important factors for obtaining the best mechanical and electrical performance.
Table 2 gives the factors and their levels.
The higher hardness value needs to further improve re-aging temperature and re-aging time with a short time to obtain better mechanical properties.
The hardness results of the ANOVA, as shown in Table 5 indicate that pre-aging and re-aging time are the most significant heat treatment factors affecting hardness performance characteristics.
The electrical conductivity results of the ANOVA (Table 6) indicate that re-aging temperature and re-aging time are the most significant heat treatment factors affecting electrical conductivity performance characteristics.

The mechanical properties were determined with use of the test according to EN ISO 6892-1:2009 standard and means of a Vickers microhardness tester.
The mechanical properties were tested during a tensile test according to EN ISO 6892-1:2009 standard.
Summary The deposited coatings were characterized in terms of their chemical composition, micro- and nanostructure and different mechanical properties: 1.
