  • Patent number: 7712222
    Abstract: A composite utility blade and method of making such a blade involves butt joining a high speed or tool steel wire to a front edge of an alloy steel backing strip. The wire defines a predetermined cross-sectional shape that substantially corresponds to the cross-sectional shape of the cutting edge of the blade. The wire is electron beam welded to the backing strip to form a composite strip defining a first metal portion formed by the alloy steel backing strip, a second metal portion formed by the high speed or tool steel wire, and a weld region joining the first and second metal portions. The composite strip is then annealed, and the annealed strip is straightened to eliminate any camber therein. The annealed composite strip is then hardened such that the first metal portion defines a first surface hardness and the second metal portion defines a second surface hardness greater than the first surface hardness.

  • Patent number: 7597971
    Abstract: The present invention relates to a thermal barrier coating material having the chemical composition of (1?n)CeO2-nZrO2-0.5R2O3, where n is in the range of 0.9?n?0 and R is selected from a group consisting of Nd, Sm, Eu, Gd, Tb and combinations of at least two among them. It possesses a thermal expansion coefficient higher than 12×10?6 K?1 from ambient temperature up to 1200° C. and superior to those of the presently widely-used thermal barrier coating materials. Even if it is subjected to long time calcinations at 1400° C. or is quenched to room temperature, it can still maintain the stable crystal structure. In addition, its thermal expansion trend matches quite well with that of the bond coating alloy. This is beneficial to the elimination of thermal stress generated between the substrate and the ceramic top coating during the thermal cycle and can significantly improve the thermal shock resistance of the coating.

  • Patent number: 7597966
    Abstract: A thermal barrier coating and deposition process for a component intended for use in a hostile thermal environment, such as the turbine, combustor and augmentor components of a gas turbine engine. The TBC has a first coating portion on at least a first surface portion of the component. The first coating portion is formed of a ceramic material to have at least an inner region, at least an outer region overlying the inner region, and a columnar microstructure whereby the inner and outer regions comprise columns of the ceramic material. The columns of the inner region are more closely spaced than the columns of the outer region so that the inner region of the first coating portion is denser than the outer region of the first coating portion, wherein the higher density of the inner region promotes the impact resistance of the first coating portion.

  • Patent number: 7585568
    Abstract: The disclosure provides an improved solar selective multilayer coating having higher thermal stability and a process therefor. According to the disclosure, a tandem stack of three layers of TiAlN, TiAlON and Si3N4 is deposited on metal and non-metal substrates using a planar reactive magnetron sputtering process. The first two layers function as the absorber and the third antireflection layer further enhances the coating's absorptance. The solar selective coatings were annealed in air and vacuum to test the thermal stability at different temperatures and durations. The coatings deposited on copper substrates are stable in air up to a temperature of 625° C. and exhibit higher solar selectivity and these coatings also show no change in the absorptance and the emittance values even after vacuum annealing at 600° C. for 3 hours. The solar selective coatings exhibit high hardness, high oxidation resistance, chemical inertness and stable microstructure.
