Ti–Al–N and Cr–Al–N have higher plastic hardness which results in better wear performance. Cr–Al–N has also been shown to have exceptionally high wear resistance and is known to have higher oxidation resistance. These attributes contribute to many times life increase in operational performance. Likewise, in real industrial applications, Cr–Al–N outperforms Ti–N and Ti–C–N by 2–3 times. In one example, tooling costs are halved and a saving of 3% in production time over the Ti–N coated tools is achieved; a significant saving in today’s highly competitive markets. Cr–Al–N is expected to play a very important part in the future of Surface Engineering, manufacturing industry and in preventing wear of critical components in a wide range of applications
