Description
| - The paper deals with evaluation of single layer PVD coatings based on Cr, Ti and Al widely used in tool application and W and WN based functionally graded coatings. In case of functionally graded coatings, the diversity of composition was due to content of N varying with the depth from the surface. Also, nitridation process was used as an “interlayer” in several cases in order to further improve the adhesion. The coatings were evaluated from the point of view of hardness and adhesion. The hardness measuring was carried out using nanoindentation and microindentation methods. Adhesion testing was performed scratch test and „Mercedes“ test for qualitative adhesion measurement. The results of scratch test showed the presence of the nitrided layer significantly increases the adhesion values of CrN coating. Also the presence of metallic interlayer in functionally graded materials further increases coating adhesion by gradually approaching its composition to the substrate. Coatings consisting of W and WN have showed very good adhesion as well. With regard to results of the scratch test and their relative higher values of the hardness, for the coatings of WN, CrAlN and duplex TiN can be assumed to have a good protective function. Results will be applied in development of functionally graded layers for functionally graded materials.
