Interlayer lying between substrate and coating layer plays an important role on these properties.
For the coating layer, both morphology and properties must be considered.
Zirconium was selected due to its unique properties including high strength and ductility [6].
Therefore, it can be concluded that both the holding time and type of interlayer coating are the important factors on morphology of the coated film.
This should be due to different mechanical properties of interlayers.

This difference in structure affects the property behavior of the products made from silica.
From here, Ross [30] took over the study and investigated the properties (especially physical and mechanical) as well as the materials used in the manufacturing process.
It is therefore necessary to investigate the physical, thermal and mechanical properties of refractory produced from nanostructured silica obtained from rice husk ash.

The reinforced concrete structures can be affected by the carbonation seriously.
The unique cavity contained in the cellulose fiber can store some free water in the cement hydration process, and this part of water will be slowly released to promote the continued hydration of cement, which can compensate the concrete shrinkage and thus improve the microstructure of concrete, the mechanical properties of concrete and the early crack resistance properties.
The bending rigidity of the structure and the mechanical properties of materials are directly related to the section thickness, and reducing the thickness of the second lining can reduce the stiffness of the second lining and distribute the loads with initial supports reasonably in usage.
Thinning the thickness of the second lining is not simply reducing it’s thickness, and the mechanical properties of it’s concrete should be improved at the same time, and that is to increase the strength grade of concrete appropriately.

Therefore, the time-varying operation mode changes the distance between the impact envelopes rather than the oscillation properties of the signal waveform.

Since the rate of flow of the powder mixture from the feeder cassette of the press machine in the case under consideration depends on its geometric parameters, physical and technological characteristics of the powders used, the influence of the design parameters of the loading device, the granulometric composition of the powders and other factors on the thickness of the outer or inner was studied layers of the resulting products.
Formula (12) allows not only to calculate the thickness of the layers of bimetallic bushings depending on the above factors, but also to solve the inverse problem, i.e. for a given thickness of the product layer, design equipment with the necessary dimensions.

In this paper, a numerical model has been developed to study the potential of use of cylinder bore surface texturing, in the form of circumferential oil grooves with different dimensions and densities, and their efficiency to improve the tribological properties of piston ring-cylinder liner tribo-system.
Towards this direction, modeling of tribological parameters, that affecting friction force is important.
These factors can be referenced from the studies of Patir [8,9].

However, the heat treatment often causes a detrimental or negligible effect on the mechanical properties as well as beneficial effect due to the change of micro structure of the steel, softening and releasing the compressive residual stress in the principle stress direction[2]-[4].
The chemical composition and the mechanical properties of as received STB340 are shown in Table 1.
The fatigue properties were discussed on the basis of fractography, hardness, residual stress and grain size for each series.
Table 1 Chemical composition and mechanical properties of STB340.
These results suggest that the circumference compressive residual stress is important factor to examine the fatigue properties of drawn steel as well as the effect of the residual stress distribution of thickness direction.

One of morphology parameters is the phase separation between donor and acceptor materials which critically affected the formation of free charges at interface area.
The phase separation condition is determined by many factors, such as the chemical properties of material, solvent, deposition conditions as well as post deposition treatment [3].
This paper proposes the use of AFM phase imaging to differentiate the component phase of heterogeneous composites based on variations in adhesion, viscoelasticity, composition and perhaps other properties.
Meanwhile, the phase images visualize of the heterogeneity of blended materials based on physical response of the scanner tip due to the variation of mechanical and adhesive properties of the thin film materials.
That is not significantly affected by the morphology of the active layer films.

X-ray diffraction (XRD) was used to investigate the structural properties of the prepared films.
It is more biocompatible because it has the same crystalline geometry and mechanical and physical properties as bio-apatite [3].
The surface morphology of the HAp nanostructure is affected by various factors, including the growing process [16].
It is also possible to achieve synthesis from solutions with brilliant properties and samples of complex contents.
