摘要： A system in a turbine engine for preventing wear on a tip shroud of a turbine blade that includes a pocket formed in a contact surface of the tip shroud and a plug that fits within the pocket and has a durable outer surface. The durable outer surface may include a cobalt-based hardfacing powder. The pocket may be machined out of the contact surface, and the plug may include a plug of predetermined size that fits snugly into the pocket. In some embodiments, the durable outer surface may substantially align with the contact surface after the plug is fitted into the pocket. In other embodiments, the durable outer surface may remain slightly raised from the contact surface after the plug has been fitted into the pocket.

摘要： A method of fabricating a machine component is provided. The method includes preparing at least a portion of a surface of a machine component for receiving a sintered preform. The method also includes forming a pre-sintered preform hybrid hardface mixture that includes combining a predetermined portion of at least one hardfacing material with a predetermined portion of at least one brazing material. The method further includes forming a pre-sintered preform. The pre-sintered preform has predetermined dimensions. The method also includes forming the sintered preform and positioning the sintered preform on the machine component. The method further includes fixedly coupling the sintered preform to at least a portion of the machine component via brazing.

摘要： A pocket structure is provided with a chamber to conceal a valuable object such as a billfold. The pocket has a front panel, a back panel and two intermediate panels. The front panel has a slit to form a pocket opening and a flap is provided to close the opening. Behind the first panel is a first intermediate panel which is secured inside the pocket to the lower seam and side seams by a row of stitching. The upper edge of the first intermediate panel extends above the slit behind the flap. The second intermediate panel is secured at its top edge to a support strip. The side edges and the bottom edge of the second intermediate panel are distal from the side edges and bottom edges of the front panel, rear panel and first intermediate panel. The space behind the rear panel and the second intermediate panel define a hidden chamber to conceal a valuable object such as a billfold.
