POLYCRYSTALLINE DIAMOND WITH IMPROVED ABRASION RESISTANCE

摘要

A cutting element and bit incorporating the cutting element is provided, as well as a method for forming the same. The cutting element includes an ultra hard material layer including chromium and carbon and exhibiting increased abrasion resistance without sacrificing toughness. The method for manufacturing the cutting element includes providing a layer of ultra hard material particles and chromium carbide over the substrate, and then sintering to form the cutting element.
