Estimating the term…
The present invention relates to a component comprising a substrate coated with a coating having a film (3,4 or 3,4,5) comprising one or more transition metals, TM, aluminium, Al, and nitrogen, N, wherein the TM and N as well as Al and N are comprised in the film forming respectively nitride compounds, wherein the transition metal nitride, TM-N, is present in the film distributed in different portions exhibiting one crystalline phase of TM-N, and the aluminium nitride, Al—N, is present in the film in different portions exhibiting one phase of Al—N, whereas the phase of the transition metal nitride is cubic, c-TMN, the phase of the aluminium nitride is wurtzite, w-AIN, and wherein the film exhibits coherent or (semi-) coherent interfaces between the c-TMN phase portions and the w-AI-N phase portions.
Component comprising:
Hot work device in particular in the shape of a tool for milling or pressing in the shape of a polycrystalline substrate coated with a PVD hard coating exhibiting stability, in particular by exhibiting high hot hardness, in the temperature range between 800° C. and 1100° C.,
Method for producing polycrystalline substrates coated with a PVD hard coating exhibiting stability, in particular by exhibiting high hot hardness, in the temperature range between 800° C. and 1100° C.
