  • Patent number: 11267053
    Abstract: A coating for carbide substrates employs a nanostructured coating in conjunction with a non-nanostructured coating. The nanostructured coating is produced by the addition of a refining agent flow, particular hydrogen chloride gas, during deposition, and may be produced as multiple individual nanostructured layers varying functional materials in a series. The combination of a nanostructured coating and non-nanostructured coating is believed to produce a cutting tool insert that exhibits longer life. Pre-treating the substrate with a mixture of compressed air and abrasive medium prior to coating the substrate and post-treating the coated substrate with a mixture of water and abrasive medium after the coating process is believed to further enhance the wear resistance and usage life of the cutting tool.

  • Patent number: 10954165
    Abstract: The present disclosure relates to polycrystalline cubic boron nitride (PCBN) with enhanced impact-resistance and wear-resistance and a method for producing the PCBN. According to the present disclosure, producing the polycrystalline cubic boron nitride with one or more kinds of protrusion-shaped borides formed on the cubic boron nitride surface may inhibits the development of cracks along the surfaces of the cubic boron nitride particles and binders, thereby to improve the impact-resistance and wear-resistance. In this way, the life-span of the machining tools may be enhanced. Further, the polycrystalline cubic boron nitride may have at least one kind of a compound composed of at least two selected from the group consisting of BN, Ti, W, Co, Zr, and Si as formed during sintering. This may allow the PCBN to have high bonding strength between the cubic boron nitride and the binder.

  • Patent number: 10245686
    Abstract: The present invention relates to a conditioning method of gas turbine engine components (e.g. compressor blades and vanes) for aerodynamic noise reduction. The gas turbine engine components are plasma treated in a high vacuum environment to generally reach a surface roughness (Ra) below 150 nanometers and in some cases below 25 nanometers. Then during the same process the components are coated using either a metallic or ceramic, hard, thin coating ranging from 100 to 3000 nanometers in thickness depending on desired surface smoothness and non-fouling properties. The same treatment combined with a surface relaxation process, which is part of a smoothing process, allows applying even up to 100 micrometers of hard coating without changes to high cycle fatigue properties and overall performance. Improved surface smoothness of the components and enhanced non-adhesiveness of the contaminants advance the quality of the flow through the gas path and compressor aerodynamic noise reduction.

  • Patent number: 10179366
    Abstract: The invention suppresses chipping of a cutting edge of a cutting tool while maintaining sharpness of the cutting edge. [Solution] A coating (20) of a replaceable knife (10) of the cutting tool is formed so that either one of a rake-face coating portion (22) that coats a rake face (14) or a clearance-face coating portion (24) that coats a clearance face (16) becomes thicker than the other. The film thickness of the thicker coating portion (22, 24) is set in a range of 0.5 ?m to 15.0 ?m, and a ratio of the film thickness of the thinner coating portion (24, 22) to the film thickness of the thicker coating portion (22, 24) is set in a range of 0.01 to 0.15.
