Researches Concerning the Improving of the Cutting Inserts Durability Using Titanium Deposition

Abstract:

It is known that in the cutting processes, due to the parameters variation of the working regimes, to the unevenness of the cutting depth, to the physico-mechanical characteristics of the processed material, to the existence or nonexistence of the coolant oiling, can appear more or less an accentuated wear of the cutting tools. All this factors have a dominant and negative influence on the durability, fact that impose being necessary taking into account some measures to increase the values of the cutting tools and/or of theirs cutting plates durability. In this sense are known various coating by deposition in vacuum researches (vacuum thermal evaporation and condensation from the vapor phase, ionic plating, vapour chemical deposition at low pressure, and so on) of some different filler materials, in thin layers, having protection role for the cutting plates, to increase the edge hardness to the superficial layer and of the tool locating and clearance surfaces and respectively, of their wear resistance. For this purpose, the authors propose to improve cutting tools durability using the deposition method by ionic plating in vacuum (PVD) of the thin titanium layers, following the cutting tools behavior in operation treated in this way. It was so studied the metal carbide cutting plates wear variation, coated with a titanium thin layer and it was determinated the cutting plates durability increasing, in comparison with those untreated. This research is usefull for predicting the lifetime of the cutting tools and/or of theirs cutting plates durability, after the titanium thin layer application, with a significant cost reduction.
