In this work, the influence of Ag additions into CrAlN coatings on surface morphology, chemical composition, structure, hardness and oxidation behaviour was studied. Increasing content decreased size morphological features produced a more compact coatings. All displayed fcc structure typical transition metal nitrides; silver phase indexed for with concentration ≥8.6 at.%. XPS results confirmed ...

CrAlN coatings have earned significant attention for use in cutting tool coating applications due to their excellent properties such as high hardness and superb oxidation resistance. It is well known that the interlayer between substrate can influence mechanical of coatings. In this work, three interlayers—CrN, CrZrN, CrN/CrZrSiN—were synthesized a tungsten carbide improve thermal stability coa...
