Dependences of the deposition rate on the
substrate temperature have been reported for a number of sputtered materials.
On the other hand the number of particles striking the cathode is proportional to the current density consequently current is much more importantly in determining the deposition rate than voltage.
The sputter-deposited Cr film shows a columnar growth of Cr films perpendicular to the steel substrate by sputtering, whereas the electroplated Cr film shows equiaxial grains.

At the same time, as can be seen from experiments [14 -16], close to surfaces there are sharp changes of the velocity and temperature fields at distances of the order of a grain diameter or less, stemming from the elevated porosity approaching the cubic-package value.
Moreover, the authors when trying to widen the range of the Reynolds number were increasing primarily the ball size instead of increasing the filtration velocity to cover a wide range of Reynolds number change.
Now determine the relation between Reynolds number and distances at which the viscosity is of importance.
The grain diameter or equivalent pore dimension can be used as a characteristic length scale in this law.
For moderate Reynolds numbers the packed bed core contribution should be taken into account.

Introduction
In comparison to other grains, rice is one of the most significant food crops in Malaysian culture.
Germination [%]=Number of seed germinatedNumber of total seeds tested×100% (1) Vigor index=Germination ×Seedling length (shoot length+root length) (2) Fourier Transform Infrared (FTIR) Spectroscopy.
The starch shape changes after neutron irradiation with 14 Gy in PTS and 35Gy in BP, becoming more spherical, shrinking and showing partial aggregation. [19] discovered that the number of small-size granules increased in both inner and outer layer endosperm of rice grain treated with 2 KGy of gamma irradiation.

The higher cooling rates during the quenching process will form smaller grain sizes, improving the hardness and strength of steel, but toughness and ductility are decreased [1].
At a high-temperature tempering of 600oC, the microstructure changes from martensitic to tempered martensitic and ferrite grain.
The greater the number of dissolved carbides in the oxide dispersion strengthened steel matrix as a solid solution will generate higher hardness [9].
This research suggests that the more brittle surface will decrease the elasticity – a reduced number of cycles characterizes this phenomenon.

Changchao Jia and co- workers synthesized Ag NWs and NPs using glycerol and EG as solvents where large number of Ag nanoparticles (NPs) and few Ag NWs were observed [14].
These geometries have definite grain boundaries which are amorphous in nature, therefore such endothermal heat at latent temperature is explicitly assigned for these domains.
Additionally, DSC highlighted the formation of significant grain boundaries, and these are more concentrated in the samples where ultrathin NWs are present and again where XRD phase distortion is seen.
Similarly, the existence of grain boundaries or amorphous domains mainly restrict electric conductivity, therefore these materials can find applications in the fabrication of diodes.

For both JP and PP samples, the polymerization index (Ip) has been calculated and the
wave number of the maximum of the Si-O stretching peak (νmax) has been collected.
JP blue, 3. white grain in JP blue, 4.
Grey grain in PP blue [C : Cassiterite, Q : αQuartz] (λexcitation = 531.9 nm).
Whatever is the colored blue shard considered in fig. 4, the Polymerization Index gave for Blue JP Ip=0.78~0.83 and Blue PP Ip=0.24, i.e. the Co ions contribute to decrease the number of connections in the Si-O-Si network.

The results show that the prepared Ni1-xZnxFe2O4(x=0.2~0.7) have good spinel structures, higher saturation magnetization (35.18~77.69 emu/g) and smaller hysteresis hoops, while Ni0.2Zn0.8Fe2O4 grains exhibit some paramagnetic behaviors, such as almost zero hysteresis and non-saturated magnetization.
The structural and static magnetic characteristics of the ferrite grains are characterized respectively by XRD and VSM.
This can be attributed to the increasing migration of Fe3+ ions from the A- to B-sites with increasing Zn content without magnetic moment in order to accommodate to the increased number of Zn ions on A-sites.
This is because the growing of the number of magnetic particles in composites leads to ferromagnetic resonance occurring in lower frequency.

A large number of experiments must be done for further researching and improving processing technics to improve the surface quality.
Comparing the processed surface layer’s organization in Fig.5 with matrix organization in Fig.6, we can see that the crystalline grain in surface layer has been refined after processing, which could improve the physical and mechanical properties of the surface layer’s organization.
Fig.7 Pit defect(×100) Fig.8 Microcracks(×100) A number of microcracks appear accompaning with the pit generation,it is shown in Fig.8.
