Since the introduction of PVD deposited Aluminium Oxide by Hauzer in 2006, this process has matured and proven itself widely in the tool market. The advantages of Al2O3 coatings, which are mainly reduction of crater wear and thermal cracking, are well-known. The coating is most often deposited with a CVD process on cemented carbides. The state-of-the-art Al2O3 PVD coating technology offered by Hauzer is not only well reproducible, it allows thicker layers to be deposited.
Proven in industrial environment
Hauzer's Al2O3 process opens new possibilities in applications where high toughness at the cutting edge is needed, but the deposition temperature of the substrate must below. Furthermore, Hauzer's Al2O3 coating system shows a factor two performance increase compared to conventional PVD coatings, especially in milling of stainless steels or difficult to cut materials. The coating is proven in industrial environments.
