The wettability of nitrogen and argon implanted WC-Co indexable knives used for wood-based material machining

Abstract

The wettability of nitrogen and argon implanted WC-Co indexable knives used for wood-based material machining. An attempt was made to examine the effect of the depth profiles of the implanted ions on the wettability of ion implanted WC-Co tools used for wood-based material machining. The tests were carried for two types of the tool surfaces, i.e. initial and polished, two commonly used gases, i.e. nitrogen and argon, and for the values of the parameters, possible to control in the case of classic ion implanters. Four depth profiles were modelled for two different values of the acceleration voltage, two for each implanted element. The modelling parameters were selected so that the two modelled depth profiles for both implanted elements were similar. The wettability tests were carried using a computer-supported test stand. The obtained results did not confirm the hypothesis about the relationship between the wettability and the position and the shape of the depth profiles.
