The application of hard and lubricious coatings to cutting tools has provided substantial benefits to the metal cutting industry by reducing wear and greatly increasing the useful life of tools. Coatings have gone through several generations of development, due to the increasing demands of the industry, such as high-speed machining, dry machining, and machining of difficult-to-cut alloys, such as superalloys and titanium. The first coatings developed were hard coatings of TiN, TiC, TiCN or aluminum oxide, and were often used in a multiple layers; materials with these coatings outperformed uncoated high-speed steel inserts, due to their superior hardness and wear resistance. However, TiN is limited in application due to oxidation at high temperatures, and TiC has a relatively low hot hardness. The next generation of coatings focused on TiAlN, with varying Ti/Al ratios. These films exhibited increased hardness and wear resistance, as well as improved chemical stability and lower thermal conductivity than the previous generation of coatings exhibited.
Despite these advances, further improvements are needed to develop coatings that will meet the needs of increasingly severe cutting environments. One approach currently under investigation is to alloy TiAlN with elements such as Cr, Y or V, which can provide coatings with higher hardness and improved oxidation resistance. In addition, in some cases, the oxides of certain elements, such as Cr or V, can be lubricious and therefore reduce tool cutting forces. Nanostructured multilayer films, such as TiAlN/CrN and TiAlN/VN represent another approach to reducing tool wear and have received considerable attention from the research community.
This Special Issue of Coatings is intended to provide a forum for original research articles as well as critical reviews on current advances in the field of coatings for machining applications. Areas of interest include, but are not limited to, advanced nitride, carbide, and oxide coatings, nanoscale multilayer coatings, nano-composite coatings, and coatings that provide reduced friction during machining applications. Aspects of research of interest include structural investigations of advanced coatings, deposition methods for coating cutting tools, laboratory testing methods, as well as machining studies and in-situ coating evaluations.
