    摘要: A cutting tool insert has a cermet body with a Co and/or Ni binder phase and a coating deposited as monolayer or as multiple and/or alternating layers of carbide, nitride or oxide. The coating has a thickness of 21-50 μm, when the inserts have a flat rake face, without or with simple chipbreakers and a Co binder phase, or has a thickness of 10-50 μm, when the inserts have a rake face land with a width of 100-300 μm with an angle of 10-25° to the rake face and a Co and/or Ni binder phase. The cermet body has more than 50 vol. % Ti-based carbonitride and less than 15 wt % and more than 6 wt % Co and/or Ni binder phase and a hardness of >1650 HV3. The disclosure also relates to the use of the coated cutting tool insert for the machining of cast iron work pieces.

    摘要: A coated cutting tool is composed of one or more layers of refractory compounds of which at least one layer is single-phase α-alumina with a pronounced columnar grain-structure and strong texture in the [300]-direction. The alumina layer is preferably deposited by CVD (Chemical Vapor Deposition) and the preferred microstructure and texture are achieved by adding a second metal halide, and a texture modifying agent, to the reaction gas. When coated cemented carbide cutting tools according to the invention are used in the machining of steel or cast iron, several important improvements compared to prior art have been observed, particularly in the machining of nodular cast iron.

    摘要: In order to obtain long time stability and usefulness for gas sensitive field-effect devices a micro structured surface is obtained below the final conducting layer. The conductive layer in the trenches or grooves will not only be protected to some extent but also they can constitute a conductive net with edges or boundaries that will remain essentially unchanged even if material is continuously lost along the borderline. The structure can be obtained in the layer laying directly below the conductive layer or in deeper lying layers with intermediate layers with even thickness.
