Effect of dry micro-blasting on PVD-film properties, cutting edge geometry and tool life in milling

The Significant Effect of Mechanical Treatment on Ceramic Coating for Biomedical Application

“…Ultrasonic vibration deformed TiN grains and reduced the porosity of the TiN-coated layer. Similar phenomena were reported when coated samples were sandblasted at different blasting pressures and times [ 13 , 14 , 15 , 16 ].…”

Pressure and temperature effects on the decomposition of arc evaporated Ti0.6Al0.4N coatings in continuous turning

“…Reasons for this include the deviation from Vegard's law and the pressure dependent stability of c-AlN. Based on this study [8], the effect of pressure is believed to be more distinct at Al compositions around 0.4 due to a shoulder of the spinodal region in the isostructural phase diagram of Ti 1-x Al x N. Since not only high temperatures [10,11] but also high stresses prevail at the rake face [12,13] of an insert during cutting, it is suspected that cutting operations are likely to give an even more pronounced spinodal decomposition compared to isothermal anneals.…”

“…Also, there exist studies using finite element method reporting larger local contact stresses during longitudinal cutting [12,13] and hence it is possible that the stresses achieved during cutting is large enough to give notable differences in the evolution of the spinodal decomposition.…”

Numerical Investigations on the Mechanical Properties of Dry End Milling

“…Domestic and overseas study indicates progressive deterioration of the ecological environment. Accordingly, negative influence of cutting fluid in traditional milling process has been put on agenda [1][2][3]. It comes to the Green Machining concept, that is, less or even no cutting fluid required in cutting process.…”
