  • Publication number: 20250154068
    Abstract: In a method of making a diamond composite a diamond green body, together with an infiltrant, is placed onto a graphite crucible and the graphite crucible is placed onto a carbon source, such that during infiltration, excess infiltrant is leaked down to the carbon source and excess infiltrant is thus avoided on the diamond composites.

  • Publication number: 20220258237
    Abstract: A method of making a 3D printed cermet or cemented carbide body including a hard phase and a metallic binder phase whereby the 3D printed green body is subjected to a sintering process including a holding step prior to a liquid phase sintering step. The sintered bodies have a reduced porosity.

  • Patent number: 11104979
    Abstract: The present invention relates to a powder mixture for three-dimensional (3D) printing of a cermet or a cemented carbide body. The powder mixture includes 65-85 wt % of porous cemented carbide or cermet particles of a median particle size (D50) of 10-35 ?m, and 15-35 wt % of a dense cemented carbide or cermet particles of a median particle size (D50) of 3-10 ?m. The present invention also relates to a method of making a cermet or cemented carbide body, the method including the steps of forming the powder mixture, 3D printing a body using the powder mixture and a printing binder and thereby forming a 3D printed cermet or cemented carbide green body and sintering the green body and to form a cermet or cemented carbide body.

  • Patent number: 11085106
    Abstract: The present invention relates to a powder for three-dimensional printing of a cermet or a cemented carbide body. The powder has 30-70 vol % of the particles that are <10 ?m in diameter. The present invention also relates to a method of making a cermet or cemented carbide body. The method includes the steps of forming the powder, 3D printing a body using the powder together with a printing binder to form a 3D printed cermet or cemented carbide green body and subsequently sintering the green body to form a cermet or cemented carbide body.
