CVD coating that triples the lifetime of cutting tools

IHI Bernex is pleased to announce the next generation of chemical vapour deposition (CVD) coatings for carbide-based cutting tool applications. This coating family is based on a proven multi-layer structure: a layer of highly structured α-aluminium oxide (α Al2O3) on top of a layer of titanium carbo-nitride deposited at medium temperature (MT-TiCN), combined with specifi c pre- and post-treatments of the cutting tool. In this article, we will show that this new generation of coatings can make tools for cutting operations last much longer than the reference coatings.
