The workpiece of martensitic stainless steel grade AISI 410 is widely used in many industrial factories, which favor the material’s properties of wear resistance [2-4].
Knight [6] studied the parameters that affect the size of stainless steel 304 using EDM.
The experiment conditions included: positive polarity, negative polarity, open circuit voltage (250 V), pulsed current (9 A), pulse on-time (12 μs), pulse off-time (12 μs), and duty factors (50%).
In addition, in the positive polarity of electrode materials, as a result, show that the fluid dielectric material is a hydrocarbon, when broken down to make carbon, having properties of negative charge and contamination of the spark runs, maintaining positive results when coating the electrodes [11].
Moreover, the white layer surface melting material also affects the integrity of the state park.

The strain is affected by substitutions in the structure and these results provide a starting point for comparison of the resulting mechanical properties.
An assessment of the properties of different bone types is required in order to ascertain whether differences are present, which may be exploited in bone replacement applications.
The relationship between mechanical properties and microstructure is thus a key focus of the current work.
In order to retain elastic properties in the material, the use of a less crystalline structure can allow bone to be produced which is less brittle.
Conclusion The study has shown that hydroxyapatite produced from the crocodile bone exhibits properties which are ideal for bone graft applications; this is seen particularly in the high porosity observed, and the low crystallinity.

Method Influence of magnetic field on properties of mine water Experiments were divided into three groups.
Factors affecting the effect of coagulation The influence of magnetic intensities on coagulation The mine water was magnetized for 4 min under the intensities of 0.1T, 0.15T, 0.2T, 0.25T, 0.3T, 0.35T, 0.4T, 0.45T and 0.5T respectly.
The three levels of each factor were chosen by single factor experiment (Factors of orthogonal experiment and their levels are shown in Table 1).
Table 1 Factors of orthogonal experiment and their levels No.
Factors affecting the effect of coagulation The influence of magnetic intensities on coagulation Under different magnetic field intensity but same time, adding same volume of aluminum chloride (PAC) solution to carry out coagulation test, the results were shown in Fig. 3.

The factors such as the speed and radius of gyration of crushing cutter drum, the shape and arrangement of crushing cutters, may directly affect the processing quality and production efficiency of the breaking machine processing banana stems.
In the determination of rotation rate, when crushing cutter radius increases, the equipment overall size enlarged, crushing cutter drum imbalance factors also increased, vibration surged[6] .

Bath Loading, which is the ratio of surface area to the volume of the bath, is a principal factor as it not only influences the deposition but also affects the phosphorous content in the deposit [1-4].
Due to the need for improved properties of microhardness, corrosion and tribological behavior, the addition of many soft and hard particles like SiC, B4C, Al2O3, ZnO2 and TiO2 in the electroless Ni-P matrix gained importance [5-7].
The mean of the selected parameters for each level of factors is determined and the delta statistics is calculated as a difference in the maximum SNR to minimum SNR of a particular parameters.

Most PM components are exposed to cyclic loading over long periods of time, and the endurable stress amplitude is an important factor considered in many applications.
Introduction Often the fatigue performance of a material is only characterized by a fully reversed bending strength amplitude for comparison purposes, neglecting a multitude of independent variables that may affect the endurance limit.
Thus, in many cases, the effect of some of these variables must be guessed, which requires higher safety factors in calculations.
Effect of Density on Fully Reversed Endurance Limits In general, a parabolic dependence of a mechanical property P on density ρ is observed [1, 2] m 00 )/(PP ρρ=
Case hardened materials have been excluded here, because in materials with property gradients the ratio is very size dependent.

POC has a great potent to form a composite material such as biodegradable bone screw in terms of improvement of the mechanical properties.
POC also possesses elastic properties.
Therefore, this polymer is composited with hydroxyapatite under the expectation to improve the mechanical properties and osteointegration.
Post-polymerization process temperature and timing affect the mechanical properties of these composites.
However, there are other factors that contribute to the high value of mechanical properties, i.e., the interaction between the polymer matrix POC and filler hydroxyapatite.

Closed extruding fine blanking parts is processed under strong hydrostatic pressure, material microstate and mechanical properties near the surface change greatly.
Introduction Closed extruding fine blanking parts is processed under strong hydrostatic pressure, material of deformation area happened great extruding cut deformation, microstate and mechanical properties near the surface change greatly, such as surface hardening is obvious, residual stress is larger, etc, which directly affect parts’ wear resistance, so it is necessary to research the wear resistance of closed extruding fine blanking parts surface to promote this technology applications.
Friction process is a very complicated process; friction coefficient is different not only with different material, but also with other factors, friction coefficient.

The correlation between four main factors such as speed, feed, depth of cut, tool condition and responses such as surface roughness, tool tip temperature were analysed.
Surface finish is the key element affecting the machining characteristics.
Several factors influence the surface finish of machined parts such as cutting conditions, geometry of the tool, cutting fluid and chip formation [4].
The cutting tool was coated with a combination of TiN+TiCN+Al2O3 manufactured by Kyocera .TiN coating applied on substrate because of its excellent lubricant properties and corrosion resistance[10].
