Alloying elements are added to steel for improving surface properties such as corrosion
resistance.
Introduction Alloying elements such as Si, Mn and Cr are added to steel products to improve their mechanical and surface properties.
Although manganese is often added to steel for controlling not only the mechanical properties but also surface properties, manganese is formed as manganese oxide in the surface layer by annealing at high temperatures [1,2].
The decrease in the density and compositional distribution in the surface layer are considered as important factors to investigate the distribution of density, composition and phase in surface area for understanding the mechanism of enrichment and oxidation of manganese.

They have a good adsorbing and desorbing properties.
There are still a few reports on the effect of optical properties on the humidity detection especially the type of metal oxide that has good electrical properties such as ZnO and TiO2 [6].
They found that the electrical properties of Sn doped is higher compare to the undoped due to the increasing of free electron but through the characterization of humidity sensing properties, the found that by the addition of Sn, the surface structure has become bigger and less in porosity and that also contribute to the low surface volume.
The type of structures depend on different kind of factors such as fabrication methods, types of dopants, types of precursors, types of stabilizers and also other parameters such as temperature and environment.
They found that the sensor has good sensing properties due to the high porosity of the surface which increase the adsorption process.

Improving the properties of low-cost materials is a good opportunity to expand their application areas.
A synergism of the matrix and the surprising properties of added particles produce properties unavailable by natural materials [1].
The graphite morphology and the metal base structure define the mechanical and the tribological properties of the cast iron, which could be changed by thermal processing [12-14] and alloying [15,16].
Influencing the shape and quantity of the graphite phase, the properties of the coating may be varied.

Introduction
Recently, the applications of nano materials were spotlighted by many researchers because of
unique and exceptional characters of nano materials such as photo-catalytic, electronic, magnetic and
mechanical behavior, etc.
The main factors to affect the mechanical properties of compacted materials are the microstructure and the pores in the compacts.
A simple real-space model consisting a set of two or three lognormal distributions of spheres per curve 2 0, 0, ln( ) ln( ) ( ) exp 0.5 i i i i R R N R N s − = − ∑ (2) (N0, R0 and s are the standard scaling factor, center and width parameters of this distribution type, respectively) with form factor 3 sin( ) cos( ) ( , ) 3 ( ) QR QR QR F Q R QR − = (3) was found to be well suited to approximate the experimental data.

The major factors which affect the efficiency of the antimicrobial additives are their migration rate and velocity in the polymer, the hidrophobity of the surfaces, and numerous interfacial phenomena.
These factors may motivate many researchers from many parts of material science because of the possibility and need of professional measure methods and instruments.
The antimicrobial property of a plastic is usually achieved by blending with antimicrobial agents, and the migration rate and velocity properties of these additives are the key factors of the effectiveness.
For the customers, it is very important that the chosen additive has to kill all microorganisms that may grow at the prospective conditions (and harmful to humans), do not migrate too fast, but do not seize in the matrix, and enhance, or at least do not worsen the technological, mechanical and optical properties of the product.
Evaluate the effect of biocide for the technological, mechanical and optical parameters of the plastic, measure the diffusion rate. 5.

Reduction in the thickness of the acetabular liner could possibly affect the load bearing capacity, wear behaviour and contact stresses of the AHJ.
Material property of the femoral head was assumed to be a rigid.
The contact area seems to be the dominant factor in determining the volumetric wear.
The smaller contact area will lead to a small sliding area so that the wear will be smaller for keeping other factors constant.
