These materials are subjected continuously to a previous phase of surface cleaning (which may be chemical or carbothermal reduction-oxidation as processes), before passing them a fairly high speed (up to 200 m/min) for the bath of zinc.
All these data were taken from [3] and [5].

Fig.1(a) exhibits that whiteness index of B.mori silk decreases to 31.45% after natural aging 15 days; and then, under natural aging 60 days, the reduction degree of whiteness index achieves to 40.96%.
In addition, the experimental data is analyzed and calculated by using curvilinear regression analysis method.

The data shown in Fig.2 illustrate the effect of cyclic acid corrosion time on the mass loss per unit area of porous Ti-48Al-xNb alloys (x=0, 2, 4, 6) in hydrochloric acid with pH=1 and pH=2, respectively.
Breakdown of the passive film and the associated pitting behavior is related to the reduction of film’s oxygen content in the region below the film.

The EBSD measurements were carried out using the TSL Data Collection V. 6.2 software.
The decrease of strain rate resulted in reduction of the volume fraction of the γ phase: after deformation at T=1150°C and ε=1 s-1 the volume fraction was found to be 15%, while only 2% of the γ phase left at a strain rate of 0.001 s-1.

Different complexity degrees of hydrogeological conditions of deposits; nonhomogeneity of filtrational properties of enclosing rock; and the lack of abundance of data concerning technogenic penetrability of the disturbed rock mass and regularities of its changes often prevent from making reliable evaluation of hydrodynamic mode within the objects being developed.
They are destructive for the majority of lithotypes of percarbonic mass; thus, its total strength is improved with the forecasting decrease in rock pressure on the powered support of a stope; – the area of active stratification of roof rocks and bedrock behind the longwall decreases repeatedly because of practically total nonavailability of tensile vertical stresses; therefore, stabilization of rock pressure manifestations takes place much earlier making it possible to forecast reduction of expenditures connected with conveyor entry maintenance in the context of its reuse; – concentration of stress intensity and areas of their effect decrease down to two times stipulating the decrease in the amount of the broken rocks within roof rocks and forming low rock pressure within the longwall.

This means, even in high temperature applications the containing organic salts and its residues, still have significant abilities for friction improvement and reduction of surface adhesion and thus, occurrence of wear.
The results have shown that a clear distinction between applied release agents could be established through evaluation of the test data from the adapted instrument.

Plastic waste will be suitable for recycling if not mixed with any other type of plastic [1], uncontaminated, [2] and dry [1], therefore it need a serial of preprocessing: plastic type identification, sorting, size reduction or grinding, washing and drying [1].
Another survey supported with plastic waste prices data of colored (or contaminated by color pigment) PET bottles waste were only 50% of the clear one, and the price of clean and clear PET bottles waste were about 45% of the price of its virgin plastic pellet [22].

This mechanism is implemented by multiple repeated impacts and also results in strength reduction.

In the phase analysis, the standard ICDD PDF-2 release 2007 data base was used.
The most probable reason of this diamond strength reduction is the occurrence of residual tangential stresses during heating and subsequent cooling due to the difference in the thermal expansion coefficients of metallized coating and diamond.
