The comparison of the DLC coating before coating, according to DLC manufacturing companies on the principle of metal cutting studies, in the normal cutting, DLC wear include the following: flank wear; rake face wear, that crescent wear; Face wear at the same time.
Comparison of DLC Coated Front Coatings
According to DLC manufacturing companies' research on the principle of metal cutting, in normal cutting, the wear of DLC mainly includes the following: wear of flank; wear of rake face, that is, wear of crescent moon; wear of front and back flank.
DLC coating technology refers to the application of a thin layer of refractory metal or non-metallic compound, DLC coating, on the surface of hard alloy or high speed steel (HSS) substrate with good strength and toughness. As a chemical barrier and thermal barrier, the friction, dispersion and chemical reaction between the DLC and the workpiece are reduced, thereby reducing the crater wear. DLC coating has the characteristics of high surface hardness, stable chemical properties, heat and oxidation resistance, good wear resistance, low friction factor and low thermal conductivity.
