Adhering layer formation and its effect on the wear of coated carbide tools during turning of a nickel-based alloy

► Workpiece material adhered onto both the rake and flank faces. ► Tool surfaces were protected from the scrubbing action of hard carbide particles. ► Adhering layer experienced a periodic “formation-stacking-plucking” process. ► The element from tool material diffused into the workpiece material. ► Adhering layer accelerated the diffusion wear process.
