Acknowledgement
Acknowledgement
First of all we want to thank the almighty Allah for the
blessing of health, knowledge and reason, and for huge opportunities gave us
during our lifetime;
We want to thank our parents for the great sacrifices they made
for us;
One of the biggest opportunities of Allah is that he made us
studying in the faculty of hydrocarbons and chemistry of BOUMERDES (ex-INHC),
where we had the pleasure of meeting great people, who sacrifice by their
money, their time and fight just to make that historical monument (which was
created in 1964) rise again despite the huge difficulties. People like Pr. M.
TAIBI, Pr. S. AISSANI, Dr. A. GUEBLI, Pr. A. ABBASSOV, Pr. A. BENBRIK, Mr. T.
HACHEMI Pr. A. BLAIDI and others, taught us indirectly what a man can do when
he has the great will and the good well to change his surrounding society;
We want to thank, particularly Pr. M. GACEB our dissertation
framer, and our honorable professor, first of all because he awakened us when
we were in a deep sleep, then he guided and helped us (and anyone who seek for
knowledge and they are few) with everything he can for the sake of science, we
wish him good health to help our successors for years to come;
We want to thank Dr. S. HASSANI our dissertation co-framer and
the responsible of Laser and Ionized Medium at the CDTA center, it was a great
opportunity to work with someone who have such a knowledge, despite the short
the time which didn't allow us to learn more from his great knowledge and
experience;
We want to thank all people who help us to fulfil our
dissertation, beginning by Pr. Abdi from the Mechanical Engineering Department
of the USTHB who allowed us to use their tribometer, our professor Dr. A.
GUEBLI who enriched us with his valuable advice, Mr. DRISS of CDTA Center who
helped us with the thin film deposition process, and all the CDTA members and
staffs;

Abstract:
Because of their nanometric dimensions, thin films have a
very high specific, a very high reactivity and exceptional mechanical, optical
and electronic properties.
The application of this technology in the internal
combustion engine industry reduces losses of friction and wear with a low loss
of material, which directly influences on the cost, whether during production
phase or during the service.
Keywords: Thin film, physical vapor deposition (PVD),
tribological properties, pistons, internal combustion engines.
