Cemented carbides coated with CVD multilayers are commonly used in metal cutting turning and milling operations. For many applications, a micro-blasting finishing procedure based on an impact treatment of the surfaces is carried out in order to smooth the coated surface and reduce sharp cutting edges. In this work, micro-blasting with corundum in aqueous solution at pressures between 0.05 and 0.3 MPa was applied to CVD TiN/Ti(C,N)/κ-Al 2 O 3 multilayer coatings deposited onto cemented carbides in order to investigate its influence on the micro-topography, microstructure and residual stresses. The results showed that the microblasting reduces the surface roughness and affects the coating thickness. TEM investigations revealed no significant changes on the microstructure of the κ-Al 2 O 3 top layer. Synchrotron X-ray investigations showed that the residual stress state of the as-deposited κ-Al 2 O 3 top layer is not affected by the micro-blasting treatment under the conditions investigated.

“…The use of a dielectric fluid mixed with nano-powders (Jahan et al, 2010) that aid in dispersing the pulse energy towards improving surface quality without affecting the removal rate may also be considered. Additional strategies to process optimization may involve such approaches as pulse shaping (Juhr et al, 2004), physical vapor deposited coatings (Casas et al, 2004), and the application of secondary processes such as thermal annealing (Casas et al, 2006) and finish micro-blasting (Qu et al, 2005). …”
