According to the sold value, 40% of all cutting tools are coated in industry today. This paper summarizes the most important application field of conventional and new coatings for cutting tools. There are two opposing development trends in the cutting industry today: (1) in dry machining the user wants to work without coolant to save the environment and production costs; (2) in high speed machining (HSC) the cutting parameters can be increased by a factor of 4–10. Aside from increasing productivity, multi-spindle heads can be replaced by one spindle, increasing the flexibility enormously. With both technologies much greater heat is produced than under normal cutting conditions. The cutting materials must have a high warm hardness and cannot work without a good heat isolation coating between the hot chips and the tool body. This paper gives an overview of the latest industrial applications of different coatings for dry and HSC cutting and characterizes the most important requirements of future coatings for cutting tools.read more

XPS investigation of preferential sputtering of S from MoS2 and determination of MoSx stoichiometry from Mo and S peak positions
TL;DR: The preferential sputtering of S from bulk MoS2 standard samples exposed to 3 keV Ar+ ion bombardment has been studied by XPS as mentioned in this paper, where the altered layer extends to a depth of 3.8 nm and is proposed to consist of a single amorphous MoSx phase in which Mo has a varying number of nearest neighbour S atoms.
