Introduction Electronic devices based on organic semiconducting materials have attracted researchers from the last decades due to low cost and large area electronic applications [1-2].
Organic semiconducting materials have been employed as an active material in different electronic devices such as organic light emitting diodes (OLED), organic thin film transistors (OTFT), strain sensors, pressure sensors, humidity sensors and organic solar cells [3-5].
For sensing applications new organic materials and their composites have been studied [1-5].

From the ensemble of wear factors acting simultaneously on the multilayer ceramic materials, associated to the coatings structures, the quick thermal shock acts most disruptive.
The furnace size permits the heating of a specimen with size of 2÷3 mm x 30 mm x 50 mm in a very short time, the time depending on the types and thickness of the used materials for a TBC protection (support material, bond coat, intermediate coat and top coat).
Types of materials used: triplex layers; metallic support (S) - Nimonic 90; bond coat (BC) – MeCrAlY; intermediary layer (I) - ZrO2• Y2O3 + Co; top coat(TC) ZrO2• 8%Y2O3.

Introduction With the wide application of nanotechnology, nanostructured ceramics appear subsequently, It is hoped that to overcome the brittleness of ceramic materials, let ceramic materials be flexibility and processability like metal.
In recent years, people tend to use high-speed flame spraying or plasma sprayed ceramic materials on the metal matrix ( such as steel ) for preparation nanostructured ceramic coatings.
Currently, at present, research, development and application of nanostructured ceramic coatings have been paid great attention by the governments and materials science community, many countries have invested a lot of money in research nanostructured coating materia’s preparation technology and its subsequent finishing technology.
