    摘要： The present invention relates to a cutting tool comprising a substrate at least partially coated with a coating, said substrate is of cemented carbide, cermet or ceramic, said coating comprising a layer of Ti(C,N), a layer of Al2O3 and there between a bonding layer. Said Ti(C,N) layer is composed of columnar grains, wherein an average grain size D422 of the Ti(C,N) layer is 25-50 nm, and wherein the Ti(C,N) layer comprises a portion B1 that is adjacent to the bonding layer, and wherein an average grain size of the Ti(C,N) grains in portion B1 is larger than the average grain size D422 in the whole Ti(C,N) layer. In the portion B1 of Ti(C,N) layer the Ti(C,N) grains has an average grain size of 130 - 300 nm.

    摘要： The invention relates to a computer-implemented method, a system, and a computer program product for predicting the properties of a coating layer CL or transmission and/or reflection properties of a substrate being coated with a coating layer CL and optionally at least one further coating layer. The invention also relates to the use of the inventive computer-implemented method for screening coating layers CL or coated substrates comprising at least one coating layer CL and optionally at least one further coating layer according to at least one criterion. Moreover, the invention relates to a substrate being coated with a coating layer CL and at least one further coating layer, wherein the transmission and/or reflection property of the substrate was derived with the inventive computer-implemented method. Finally, the invention relates to a client device for generating a request to initiate the prediction of at least one property of a coating layer CL or at least one transmission and/or reflection property of a substrate being coated with a coating layer CL and optionally at least one further coating layer at a server device.
