The paper deals with the tribological properties of investigated types of hard-faced materials under erosive wear conditions.
From achieved results concluded that inclination angle is one from determining factors on to material’s wear measure.
Nevertheless, the abrasion resistance of a hardfacing alloy depends on many other factors such as the type, shape and distribution of hard phases, as well as the toughness and strain hardening behavior of the matrix [3].
Their application allows the creation of suitable combination of surface layers and support components properties.

Analysis of mechanical properties of diamond-like carbon (DLC) films based on experimental designs was reported to optimize characterize by a magnetron sputtering.
Many of these films have been found to display unique mechanical, physical and electronic properties and thus possess great potential for application in tribology, as well as protective and decorative coatings.
Accordingly, traditional methods with characteristic mechanical properties have more difficulty in achieving good results.
Most of the factors have three levels, but Factor A (Material of depositions) has two.
An analysis of variance (ANOVA) was progressed with S/N ratios to detect the effects of factors and was used to examine the influenced factors for quality of films efficiently.

Dynamic Mechanical Analysis (DMTA) is widely used as a technique to find out the interfacial characteristic of heterogeneous polymer systems under temperature dependent dynamic properties [4].
However, no study appears to have reported of the effect alkaline treatment towards the DMTA properties and how this affects to the performances.
The DMTA properties were determined by using Perkin Elmer D8000 Analyzer.
The behavior of increasing damping peak in the tan delta curves is attributed by decreases of amount of matrix incorporated with fibres [7].This suggests the treated fibres have gain benefits improving their mechanical properties.

Factors such as microstructural characteristics, mechanical performance, production efficiency, and cost must be considered.
Furthermore, the directional solidification inherent in the process can result in anisotropic mechanical properties, affecting performance depending on the orientation of the part.[12] Microstructurally, 316L stainless steel produced by DED exhibits fine grains due to rapid cooling rates, which enhances strength and hardness.
Microstructurally, cast 316L stainless steel often exhibits a dendritic grain structure with potential segregation of alloying elements, which can affect corrosion resistance and mechanical properties.
This can lead to segregation of alloying elements at grain boundaries, affecting corrosion resistance and mechanical properties.
· Mechanical Properties: DED components generally have superior mechanical properties compared to cast parts

The test results prove that the vibration damping structure can effectively isolate the interference signal produced by working platform without affecting the sensitivity of hydrophone obviously.

Rubber is widely used in many engineering fields to eliminate vibration and noise due to its integrated mechanical properties, which includes adjustable modulus, high intrinsic damping, excellent tolerance of large strain and carry capability under deformation.
Apart from affecting its mechanical properties, these intermolecular forces boost the aggregation of soft segments, and then micro-phase separation structure is produced.
By adjusting the ratio of rubber components and processing conditions, the soft bearing’s loss factor can be further increased to eliminate vibration noise without affecting the normal operation of hydrophone to extract useful signal.

Some factors can
affect the experimental results of sandglass extrusion, such as extrusion ratio, number of extrusion,
extrusion temperature, friction and free space in mould cavity etc.
These factors have different effects on material microstructures, properties and defects.
Wang designed a set of mould and relative technology called "sandglass extrusion" (SE) (because the shape of mould cavity looks like a sandglass), then investigated the method, the development of the microstructures, the mechanical and superplastic properties of the material treated by SE [7-9] with present authors.
Some factors can affect the experimental results of SE, such as extrusion ratio, number of extrusion, extrusion temperature, friction and free space in mould cavity etc.

The tensile elasticity of the fiber web was mainly impacted by the properties of fibers.
Changing the arrangement of fibers and web organization, the mesh structure could be changed after spun-lacing and thus affecting both the longitudinal and transverse elastic recovery property of spun-laced nonwovens.
Further consideration should be taken into the external factors in web forming, such as jet energy, jet hole size, number of fibers, etc.

Some researchers had proved that there are many factors affecting the PTC property of polymer-based composites.
These factors include the property and structure of polymer, the type, structure, morphology, surface property and concentration of fillers, and the distribution of fillers in polymer matrix [6-9].
The external electric field and magnetic field can change the structures of polymer and improve the dielectric and mechanical properties of polymer.
This will cause a decrease of PTC intensity and mechanical properties, an increase of brittleness and a deterioration of processability of composites.
The PTC composites with magnetic field treatment present good comprehensive properties

Their exploitation serves to improve the mechanical and physical properties of a new material dedicated to filling and insulation in buildings.
Several research studies have been carried out on the mechanical and physical properties of concrete and mortars.
The extraction of fibers is carried out manually to avoid any kind of degradation of mechanical properties that may occur in the case of mechanical and chemical extractions [10].
All these factors show the decrease in compressive strength [13].

The cooled material has dissimilar mechanical properties for each of discrete element.
Thus the mechanical properties (after simulation of load) will completely have different values when influence of injection molding is included. 1.
No factor is insignificant.
E) Export of the mesh with material properties of each element.
The unique combination of input factors (injection time, melt temperature and mold temperature) was set for each experiment.
