Aspects Regarding the Widia Plates Behaviour Covered with TiN During the Cutting Process
MetadataShow full item record
The microscopic property that depends on the interfacial structure and on the tension to which the interface is submitted is called adherence. The strong connection in the interfacial area, low tension gradients, the absence of cracks and of degradation in the course of time are properties that define a good adherence at the layer-underlayer interface. The good adherence of the thin layer to the underwear implies the non- deterioration in normal conditions or while tensions application of the interfacial area. In order to establish the degree of adherence of the tin titanium – nitride layers deposed on the widia plates, there were researches made about the behaviour of the covered plates during the cutting process. In this way the dependence between the durability (T) of the widia plates and the cutting speed (v) was determined as a result of experiments.
