    Abstract: A coated cutting insert 10 for removing material from a workpiece is disclosed. The insert 10 a substrate 12 and a wear-resistant coating including an α-alumina layer 15 and a Zr- or Hf- carbonitride outer layer 16 deposited on the α-alumina layer 15. The Zr- or Hf- carbonitride outer layer 16 is subjected to a post-coat wet blasting treatment. The wet blasting changes the stress condition of the alumina coating layer 15 from an initial tensile stress condition to a compressive stress condition.

    Abstract: A coated ceramic cutting insert (20) for removing material from a workpiece, as well as a method for making the same, that includes a ceramic substrate ((40, 40A, 40B) with a rake surface (28) and at least one flank surface (30) wherein a cutting edge (32) is at the juncture therebetween. A wear-resistant coating scheme (50, 82) that includes at least one exposed alumina coating layer (50, 60, 62, 82) which exhibits a blasted stress condition ranging between about 50 MPa (tensile stress) and about - 2GPa (compressive) as measured by XRD using the Psi tilt method and the (024) reflection of alumina. The exposed alumina coating layer (50, 60, 62, 82) is the result of wet blasting a titanium-containing outer coating layer (54, 54A, 54B) region from the surface of the alumina-containing base coating layer region (50, 50A, 50B).

    Abstract: In one aspect, articles are described herein comprising wear-resistant claddings. An article described herein, in some embodiments, comprises a metallic substrate and a cladding adhered to the substrate, the cladding including a metal matrix composite layer comprising at least one hard particle tile having a pore structure infiltrated with matrix metal or matrix alloy. Infiltration of the pore structure of the hard particle tile by the matrix metal or alloy can render the tile fully dense or substantially fully dense.

    Abstract: A coated polycrystalline cubic boron nitride cutting insert (28, 58), which has a polycrystalline cubic boron nitride substrate (70, 126) with a cutting edge (34, 66). A wear-resistant coating scheme (74, 74A) is on the polycrystalline cubic boron nitride substrate. The wear-resistant coating scheme includes an inner coating layer region (94, 150) and at least one exposed alumina coating layer (84, 84A, 138). The exposed alumina coating layer (84, 84A, 138) exhibiting a post-blasted stress condition with stress ranging between about 50 MPa (tensile stress) and about - 2GPa (compressive stress) as measured by XRD using the Psi tilt method and the (024) reflection of alumina. The exposed coating layer (84, 84A, 138) is the result of wet blasting an outer titanium-containing coating layer (86, 88, 140, 142) from the surface of the alumina-containing coating layer region (84, 138).
