“…These studies showed that MoS 2 coatings deposited with metal addition gettered oxygen partly during the wear experiments and enhanced the friction coefficient and wear resistance of the coatings relatively [16,25]. It was also determined that MoS 2 /metal composite coatings were hard and less sensitive to water vapor than pure MoS 2 coatings [3,26]. Among these metal elements, incorporation of Ti to MoS 2 has been introduced to the market as MoST™ by Teer Coatings Ltd [16].…”

“…Also, Ti can be used as an interlayer which led to an improvement in coating adhesion [27]. This situation led to incorporation of titanium into the coating itself, resulting in improved friction and wear properties [3,26].…”

“…These materials also show enhanced "electron emission" and hence these are useful for developments of electron emission devices [12]. The higher values of modulus and hardness attract their applications in wear control in mechanical industry [13][14][15][16]. The oxides of these materials have applications for gas sensing [17] as well as electro chromic devices [18,19].…”

In this paper we report, for the first time, a new approach for synthesis of high quality faceted microcrystalline coatings of molybdenum (Mo), tungsten (W), their carbides and composites. These studies are carried out using Hot Filament Chemical Vapor Deposition (HF-CVD) method wherein parent materials (Mo and/or W) are taken in the form of wires (~0.5 mm dia) and are heated to a high temperature (T F ~ 1500-2000 C), in ambient of "oxygen (O 2) diluted hydrogen (H 2) gas". Due to high filament temperature (T F), a series of pyrolytic reactions take place. Firstly, the gasification of wire material (Mo and/or W) occurs in the form of its oxide. The oxide molecules reach the substrate which is kept underneath the filament assembly. Secondly, molecular hydrogen gets dissociated into atomic hydrogen and subsequently reaches the substrate to react with oxide molecules, finally leading to the precipitation of a pure metal. This method can also be used, in situ, to convert metallic coatings into their carbides and/or composites. The method offers many other attractive features, which can not be rendered by the conventional CVD/PVD methods. The results are discussed in terms of temperature induced "Red-ox" reactions.

“…Hence, coatings consisting of multi-layers to meet the requirements in demanding applications can be a possible solution. For example it has been previously reported that co-sputtering of MoS 2 with Ti has resulted in a dense coating with good friction and wear properties [1][2][3]. Fox et al [1] have described the development of these MoS -Ti coatings and also compared the performance of…”

The use of surface coatings is emerging as one of the most important approaches in reducing friction and wear in various tribological applications. Even though single layer coatings have a wide range of applications, the performance of the single layer alone may not always be adequate to meet the desired tribological property requirements. Hence, coatings consisting of multi-layers to meet different property requirements in demanding applications are required. In this study, the tribological properties of a graded composite multilayer coating with a specific layer sequence of MoS :Ti/MoS 2 :TiBN/TiBN/TiB 2 /Ti deposited on tool steel substrate have been investigated at temperatures of 40°C and 400°C respectively. The experimental results from the tests at 40°C have shown that the friction coefficient value ranges between 0.02 and 0.034. It was found that the deposition parameters influenced the friction and durability of the coatings. Higher substrate bias was found to result in higher friction and the coating deposited at high substrate bias and low N flow showed the lowest durability. The friction coefficient and durability of the coatings were found to be highly dependent on temperature. At high temperature, the friction coefficient increases almost three fold and the durability decreases significantly.
