Abstract

The present work aims to improve tool life of blanking punches by physical vapor deposition (PVD) coatings. TiN, TiCN, TiAlN and CrN coatings were tested. Hardness, wear and fatigue tests were carried out. Coatings were deposited on the surfaces of blanking punches that were hardened to have 60-62 HRC hardness, then groud to have 0.4 µm Ra surface roughness. The punches were tested by A10 washer stamp. The test results revealed that, TiAlN coated punch showed the highest hardness values, lowest wear rate and longer fatigue life. Besides, TiAlN coated punch showed the highest wear resistance. A mathematical model was introduced to correlate hardness, wear and fatigue of the tested punches. An agreement between values derived from the mathematical model and the experimental results was found.
