Latest Patents
Jan Åkerman's latest patents focus on a cemented carbide body with improved high temperature and thermomechanical properties. This invention provides a cemented carbide grade for rock excavation purposes, consisting of 88-96 weight % tungsten carbide (WC), preferably 91-95% weight % WC. The binder phase is composed solely of cobalt or a combination of cobalt and nickel, with a maximum of 25% of the binder being nickel. Additionally, small amounts of rare earth metals, such as cerium and yttrium, can be included, up to a maximum of 2% of the total cemented carbide. The WC grains are rounded due to the coating process with cobalt, avoiding recrystallization or grain growth, which results in unexpectedly high thermal conductivity. The average grain size is specified to be between 8-30 µm, with a preference for 12-20 µm. Furthermore, the maximum grain size does not exceed twice the average value, and no more than 2% of the grains in the structure are less than half of the average grain size.
