This paper presents a concept of combining hard CrN (or CrSiN) and soft Ag lubricating materials in a nanoscale multilayer structure. The CrN/Ag and CrSiN/Ag multilayers are synthesized by reactive direct current (DC) magnetron sputtering techniques.

CrN and Cr–Si–N films have been deposited by means of reactive magnetron sputtering in an Ar + N 2 mixture (20 and 10 sccm respectively) at a constant RF bias voltage of − 200 V. The silicon content of the films was controlled thanks to silicon

AlCrN and AlCrSiN coatings were deposited on M2 steel by cosputtering of metallic Al-Cr (70–30 at.-%) and Si targets in reactive argon–nitrogen gas mixtures. The Si content in the film varied from 0 to 1.7 at.-%, as a function of the current appl

According to its high temperature stability, low friction coefficient against metals and relatively high hardness, α-Al2O3 is a good candidate for high performance coatings. However, Al2O3 is brittle which limits its application as a protective coat

Titanium nitride or dioxide coatings have been reactively sputter-deposited under unstable sputtering conditions using a cold or hot target. We have shown that increasing the sputtered titanium flux in cold target sputtering (CTS), by increasing eith

Cr–N and Cr–Si–N coatings have been deposited with two nitrogen flow rates, 6 and 10 sccm, for a constant argon flow rate of 20 sccm with various amounts of silicon, in an ALCATEL SCM 650 sputtering system. DC and pulsed DC were used to power t

Diamond-like carbon (DLC) coatings exhibit excellent tribological properties in dry sliding conditions. Two recently developed carbon-based coatings (Graphit-iC and Dymon-iC) have been shown to exhibit very high sliding wear resistance (specific wear

Low-frequency modulation of the discharge current is as a convenient way of overcoming the drawbacks associated with unstable behaviour, i.e. the hysteresis effect, often encountered in reactive magnetron sputtering. In this paper, we present the mai

Low-frequency modulation of the discharge current constitutes an efficient means of achieving high rate deposition of stoichiometric ceramic compounds in spite of the so-called unstable sputtering conditions. The main trends of the process are review

Reactive magnetron sputtering often presents an unstable sputtering mode preventing high rate deposition of stoichiometric ceramic films, the origin of which is mainly due to the avalanche-like target poisoning over a critical reactive gas partial pr
