Abstract.
But, to know the relationships between textures and longevity of TiN coated films is a very difficult and complicated problem, because it is related to the mixed characteristics of the TiN coated layers and substrate materials, etc..
The counterpart ball material was alumina, the size of the ball was 5mm diameter, the applied force was 200g and the sliding speed was 0.045m/sec.
In the same substrate materials, the i pass (passive currents) of (115) texture of TiN coated layer is lower than that of (111) texture.

Abstract.
JIN et al. [6] made partial hydrophilic finishing on the PP spun-bonded nonwovens materials considering Sanitary napkin and paper diaper need excellent characteristics of lateral infiltrate.
Studying on feasibility and effect factors of partial hydrophilic finishing using the single factor experiments and orthogonal experiments, the results of study display that hydrophilicity and softness of nonwovens materials are optimal when the concentration of hydrophilic additive is controlled at 1% ~1.5%.

One used various combinations of materials such as: basic material-basic material, deposited coating-deposited coating.
Fig. 3 Evolution of the friction value in the case of mixed lubrication working conditions of the roll with a NiAlSi coating – basic material drag This sample had the best contact fatigue behavior, a fact which is pointed out by the aspect of the rolling path of Fig. 4.
The transversal section aspect, after the contact fatigue, presents the distribution of the oxides inside the material and micro fissures emerged at the interface of the neighboring splats.

It is known that hot plastic deformation processes such as extrusion, rolling and forging of the discontinuously reinforced metal matrix composites can enhance bond between matrix and reinforcement, break up of particle agglomerations, decrease or elimination defects of composites, all of which contribute to improve the mechanical properties of these materials [1-3].
Composites exhibited higher 0.2% proof stress and tensile strength values when compared with unreinforced materials in peak aged conditions.
An average of three results was taken as strength of each material.

However, as for the tensile strength and fatigue resistance of the materials, inhomogeneous structure is usually not preferred because there is high stress concentration around the end of the filler particles while a large portion of rubber matrix is not reinforced.
It is therefore worthwhile to introduce a second filler into the rubber/clay nanocompounds, in order to further improve material properties.
