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.
