The effect of wet blasting as a pre-deposition treatment for thick TiAlN PVD coating on machining performance

Edge preparation techniques are known to be an effective method to adjust the microgeometry and improve the mechanical properties of cutting tools. These techniques can also be used on tools prior to coating deposition to further improve the coating quality on the cutting edge and, consequently, tool life. In this research, wet blasting was used on indexable turning inserts to adjust the cutting-edge radius in order to address quality issues …
