Abstract

Carbon nitride (CNx) coatings exhibit a wide range of very attractive properties (such as low friction and wear, high hardness, good thermal and chemical stability, etc.) which make them very suitable for demending mechanical and tribological applications. During sliding against uncoated silicon nitride (Si3N4) and CNx-coated Si3N4 in gaseous nitrogen atmosphere or in nitrogen gas flow, it provides superlow friction and wear. The beneficial effect of nitrogen on reducing friction and wear is much more pronounced if the portion of the runningin period is carried out in air or in oxygen before introducing nitrogen to the sliding interface. In this chapter, we will provide a comprehensive overview of the unique tribological properties of CNx coatings in general and the effects of various gaseous environments on these properties in particular.
