By analyzing experimental data, it was found that wear patterns of nano-TiAIN coated cemented carbide tools in high speed milling AerMet100 steel included rake face wear, flank wear, breakage of coating, micro-chipping of cutting edge, boundary groove wear, conchoidal avalanche. Wear mechanisms included abrasion, adhesion, diffusion and chemical wear.
