Impregnated diamond matrices with matrix layer



IDP manufactures a range of impregnated diamond matrices with matrix layer metal bonds that range from hard, abrasion-resistant types to soft, ductile types. In general, a hard, abrasion-resistant matrix would be used to drill a soft, abrasive, unconsolidated formation while a soft, ductile matrix would be used to drill an extremely hard, non-abrasive, consolidated formation. The idea is to match the bit matrix hardness to the formation hardness in order that the metal bond of the matrix layer will erode at a controlled rate during normal drilling operation. This controlled erosion of the matrix layer metal bond will in turn continually expose new layers of sharp synthetic diamonds until the matrix layer of the bit crown is totally consumed.
