Latest Patents
One of her latest patents is the PVD Al2O3 coated cutting tool. This invention describes a coated cutting tool designed for metal machining. The coating consists of one or more layers of refractory compounds, with at least one layer of fine-grained, crystalline γ-phase alumina, Al2O3, featuring a grain size of less than 0.1 µm. The Al2O3 layer is deposited using a bipolar pulsed DMS technique (Dual Magnetron Sputtering) at substrate temperatures ranging from 450°C to 700°C, preferably between 550°C and 650°C, depending on the specific material of the tool body. The identification of the γ-phase alumina is achieved through X-ray diffraction, with reflexes from the (400) and (440) planes occurring at the 2θ angles of 45.8 and 66.8 degrees when using Cu radiation. The alumina layer is strongly textured in the [440]-direction and is virtually free of cracks and halogen impurities. Additionally, the Al2O3 layer provides the cutting edge of the tool with an exceptionally smooth surface finish.
