Abstract: Thin malleable metal foil is packaged in tape rolls or single sheets and is used to repair worn metal parts, such as rotatable shafts, surfaces subject to wear from lateral motion, and rusted or corroded sheet metal. The tape may also be used as a strapping tape to hold broken machinery parts together until a replacement part is obtained. The tape is designed to be temporary in nature, thus to serve as a means for effecting an emergency repair until a more permanent solution can be obtained. The tape may be selectively tapered along its width when it is used to repair a worn portion of a rotatable shaft, since the tapering will permit the tape to conform to a concavely-shaped worn surface in an even manner. To facilitate the degree of tapering, the tape surface may be provided with angulated scribe lines so as to permit a user to cut the desired taper depending upon the concaveness of the worn surface to be repaired.

Abstract: This invention is directed to improving the thermal shock resistance of a ceramic layer. The invention is particularly directed to an improved abradable lining (16) that is deposited on a shroud (14) forming a gas-path seal in turbomachinery.Improved thermal shock resistance of a shroud is effected through the deliberate introduction of "benign" cracks. These are microcracks which will not propagate appreciably upon exposure to the thermal shock environment in which a turbine seal must function.Laser surface fusion treatment is used to introduce these microcracks. The ceramic surface is laser scanned to form a continuous dense layer as shown in FIG. 2. As this layer cools and solidifies, shrinkage results in the formation of a very fine crack network.The presence of this deliberately introduced fine crack network precludes the formation of a catastrophic crack during thermal shock exposure.
