Abstract
A method of making a cemented carbide based composite article includes the steps of placing at least one cemented carbide insert into a mould, and casting the cemented carbide insert in an iron matrix in the mould to form the cemented carbide based composite article. The insert may be a 3D printed scaffold having an open framework or a plate having an array of surface dimples configured to receive bulk material fines during use.
Claims9
