“…The low hardness value can also be related to the low duration of Ar + ion bombardment. Ar + ion bombardment can be responsible for creating residual compressive stresses leading to higher hardness and also it can act as an obstacle to dislocations movement and so the hardness will be improved [19]. The elastic modulus of the uncoated piston skirt is lower than that of W-Ti-N on both substrates.…”

Tungsten-Titanium-Nitrogen (W-Ti-N) thin film, 1.1 μm in thickness, was deposited on Aluminium-Silicon (Al-Si) and stainless steel substrates using the Physical Vapour Deposition (PVD) sputtering system in order to study a new way to improve the tribological properties on engines piston skirts. Tribological test results showed very interesting friction coefficient and wear rates compared to uncoated piston skirt samples. The average value of the friction coefficient was approximately six times lower than that of the uncoated piston skirt samples. Wear rate was considerably lower. In addition W-Ti-N showed interesting corrosion behaviour.
