Abstract: A coated ceramic cutting insert for removing material from a workpiece, as well as a method for making the same, that includes a ceramic substrate with a rake surface and at least one flank surface wherein a cutting edge is at the juncture therebetween. A wear-resistant coating scheme that includes an alumina-containing base coating layer region, which has at least one exposed alumina coating layer, deposited by chemical vapor deposition on the substantially all of the surfaces of the ceramic substrate that experience wear during removal of material from the workpiece. The exposed alumina coating layer exhibits a blasted stress condition ranging between about 50 MPa (tensile stress) and about −2 GPa (compressive) as measured by XRD using the Psi tilt method and the (024) reflection of alumina. The exposed alumina coating layer is the result of wet blasting a titanium-containing outer coating layer region from the surface of the alumina-containing base coating layer region.

Abstract: A coated article such as a coated cutting tool or coated wear part, which includes a substrate and a coating scheme on the substrate. The coating scheme has a titanium-containing coating layer, and an aluminum oxynitride coating layer on the titanium-containing coating layer. The aluminum oxynitride includes a mixture of phases having a hexagonal aluminum nitride type structure (space group: P63mc), a cubic aluminum nitride type structure (space group: Fm-3m), and optionally amorphous structure. The aluminum oxynitride coating layer has a composition of aluminum in an amount between about 20 atomic percent and about 50 atomic percent, nitrogen in an amount between about 40 atomic percent and about 70 atomic percent, and oxygen in an amount between about 1 atomic percent and about 20 atomic percent. The method of making the coated article includes a step of providing a substrate and depositing an aluminum oxynitride coating layer from a gaseous mixture that includes nitrogen, aluminum tri-chloride, ammonia, carbon dioxide, hydrogen chloride, optionally carbon monoxide, optionally argon, and hydrogen.
