Title: Susanne Norgren: Innovator in Cutting Tool Technology
Introduction
Susanne Norgren is a prominent inventor based in Vastberga, Sweden. She has made significant contributions to the field of cutting tool technology, holding 2 patents that showcase her innovative approach to materials and manufacturing processes.
Latest Patents
One of her latest patents is for a coated cutting tool. This invention relates to a coated cutting tool that includes a chromium-containing cemented carbide substrate. The substrate consists of tungsten carbide (WC), a binder phase, and a gamma phase. The cemented carbide features a gradient surface zone with a thickness ranging from 2 to 100 μm, which is enriched in the binder phase and depleted of the gamma phase. Additionally, the cemented carbide contains MC carbides in an amount between 0.5 to 7 area percent measured in the bulk, where M represents elements such as chromium, tungsten, and at least one binder metal. The coated cutting inserts demonstrate improved edge line toughness.
Another notable patent is for a gradient cemented carbide body and the method of manufacturing it. This disclosure outlines a method for creating a cemented carbide mining insert that possesses a chemical and hardness gradient. The process involves providing a green mining insert compact formed from a first powder that includes a WC-based hard phase, along with optional additional hard-phase components and a binder. A second powder containing a grain refiner compound and/or a carbon-based grain growth promoter is applied to at least one portion of the surface of the green mining insert compact. The green compact is then sintered to produce the final cemented carbide mining insert, which includes chromium in a mass ratio of Cr to binder ranging from 0.01 to 0.3.
