    摘要: 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.

    摘要: A femoral reamer (100) can include a base material (304) and a coating (302) disposed on the base material. The coating can be harder than the base material and, as a result, the femoral reamer can wear more slowly than if the coating was absent. The coating can be a different color than the base material. When the coating is worn off, such wear can be easily observed from a visual inspection of the femoral reamer. The coating can have an initial thickness (i.e., a thickness prior to use) that is related to a tolerance on a size and/or a shape of a hole drilled by the femoral reamer. When the coating is worn off, the size and/or the shape of the hole drilled by the femoral reamer may be at or near an edge of a specified tolerance range. The femoral reamer can be part of a kit and a method.

    摘要: An improved cutting tool 10 for rotary cutting is described, The tool has a holder 12, a seat 26 and a cutting insert 32. The seat 26 is provided with a wear indicator 30 which creates sparks when the wear indicator comes in contact with the workpiece. The wear indicator 31 is also able to be located in the cutting insert 33. The sparks alert the user of potential future damage to the holder due to contact with the workpiece.
