✦ Synopsis
In order to provide sufficient wear protection on tools, which supports to increase productivity in the manufacturing processes, the substrates can be coated with different hard material layers. High hardness is one important thin film property to get an optimal wear protection of tools, but if the working temperature exceeds an upper limit the hardness of the thin film is strongly reduced. The concrete valuation of the decrease in the hardness depends on the coating materials. For the standard TiAlN-coating, the maximum operating temperature conditions is therefore limited to 850 °C. Nowadays for high speed cutting and dry or low lubricant cutting applications, a maximum temperature of about 1100 °C [J.
