Assessment of the tribological and wear performance of new duplex AlTiN-based coating systems at high temperatures when threading super duplex stainless steel

During machining, a significant amount of energy is transferred at the cutting interfaces (tool/chip and tool/workpiece) to perform a cut. Tribology is the science of how surfaces interact when cutting metal, describing the physics and mechanics characterized by high loads and temperatures at the cutting interface. This paper explains how to determine the energy consumption required to make a cut, considering different combinations of cutting …
