Multilayered coated cutting tool
The present invention relates to a cutting tool comprising a body of sintered cemented carbide or cermet, ceramic or high speed steel on which at least one of the functioning parts of the surface of the body, a thin, adherent, hard and wear resistant coating is applied. The coating comprises a laminar, multilayered structure of refractory compounds in polycrystalline, non-repetitive form, MX / NX / MX / NX where the alternating layers MX and NX are metal nitrides or carbides with the metal elements M and N selected from the group consisting of Ti, Nb, Hf, V, Ta, Mo, Zr, Cr, Al and W. The sequence of individual layer thicknesses is essentially aperiodic throughout the entire multilayered structure, and layer thicknesses are larger than 0.1 nanometer but smaller than 30 nanometer, preferably smaller than 20 nanometer. The total thickness of said multilayered coating is larger than 0.5 mu m but smaller than 20 mu m.

Laminated shingle
Laminated shingles are manufactured from roll stock roofing material that is wider than that used to make similar laminated shingles. The roll stock includes longitudinal edge strips having a reduced thickness. The roll stock is cut into strips of tabbed top sheets and backing sheets. The strips of material used for the backing sheets are at once wider than commonly used in the industry, and include the longitudinal edge strips of reduced-thickness material. Because the backing sheet is wider two rain seal strips are laid down on the backing sheet prior to being laminated to the tabbed top sheet. The backing sheets are laminated to the tabbed top sheets with the longitudinal edges aligned. The wider backing sheet provides a substantially wider nail zone. In addition, since it allows for a second rain seal strip, provides somewhat more protection against leakage. The portion of the backing sheet that comprises the added width is relatively thinner than the remaining portions of the sheet. Paired shingles may therefore be oriented adjacent one another in opposite directions and stacked and bundled. The total thickness of the stack will be the same throughout the stack, so the stack of shingles is flat.

7FAstage 1 abradable coatings and method for making same
InactiveUS20050003172A1Minimal wearReduce gas leakageMolten spray coatingEngine manufactureLeading edgeGrid pattern
A method of applying a profiled abradable coating onto a substrate in which an abradable ceramic coating composition is applied to a metal substrate using one or more coating application techniques to produce a defined ceramic pattern without requiring a separate web or grid to be brazed onto the substrate. The invention is particularly designed to withstand the higher operating temperatures encountered with the stage 1 section of 7FA+e gas turbines to allow for increased coating life without significant deterioration in structural or functional integrity. Typically, the grid pattern coating begins approximately 0.431″ after the leading edge of the shroud, and ends approximately 1.60″ before the trailing edge of the shroud. In the case of diamond-shaped patterns, the grid pattern will be about 0.28″ long and 0.28″ wide, with an overall thickness of about 0.46.″ The coatings thus provide the required levels of abradability and leakage performance and may be applied as a chevron or diamond pattern with the shape oriented such that the diagonals run perpendicular and parallel to the sides of the shroud.
