Effect of ductile layers in mechanical behaviour of TiAlN thin coatings

TiAlN is a very popular coating for high-speed cutting manufacturing processes. Nevertheless, it is important to develop research work concerning the durability of this kind of coatings. Design and producing coatings based on TiAlN with interlayers of metal with low elastic modulus, like Al, Ti or Cu may contribute to improvement of cutting efficiency. Interlayers with 80 nm of thickness, in alternateness with TiAlN with different periods were...
