Effects of TiN single layer coating on the wear of ZTA cutting inserts and surface roughness of workpiece
Single layer TiN coated and uncoated zirconia toughened alumina (ZTA) cutting inserts were fabricated and used to machine stainless steel 316 in a turning process. The powders of alumina, yttria partially stabilized zirconia and magnesia were mixed and uniaxially pressed into rhombic cutting tool in...
