description Cutting elements include a substrate, a thermally stable polycrystalline table comprising a superhard material secured to the substrate, and a layer of metal interposed between, and attaching the substrate and the thermally stable polycrystalline table. Methods of forming a cutting element include providing a thermally stable polycrystalline table in a mold, providing a layer of metal on the thermally stable polycrystalline table, distributing a mixture of particles comprising a plurality of hard particles and a plurality of particles comprising a matrix material on the layer of metal, and heating the mold while applying pressure to the mixture of particles to cause the mixture of particles to coalesce and form a substrate and at least partially melt the layer of metal to flow and wet the thermally stable polycrystalline table and the substrate to form an attachment therebetween. Los elementos de corte incluyen un sustrato, una faceta superior policristalina térmicamente estable que comprende un material superduro asegurado al sustrato, y una capa de metal interpuesta entre, y que conecta el sustrato y la faceta superior policristalina térmicamente estable. Los métodos para formar un elemento de corte incluyen proporcionar una faceta superior policristalina térmicamente estable en un molde, proporcionar una capa de metal sobre la faceta superior policristalina térmicamente estable, distribuir una mezcla de partículas que comprende una pluralidad de partículas duras y una pluralidad de partículas que comprende un material de matriz en la capa de metal, y calentar el molde mientras se aplica presión a la mezcla de partículas para provocar que la mezcla de partículas se fusione y forme un sustrato y funda por lo menos parcialmente la capa de metal para que fluya y moje la faceta superior policritalina térmicamente estable y el sustrato para formar una conexión entre los mismos.
