PSP™ is a customized blend of superalloy and braze powders in either a plate form or specific shape allows selective build-up of worn surfaces to be achieved quickly and efficiently offering savings in time and cost. Extrudable paste allows for application in difficult to reach areas and a brushable paint form is used for sealing deep or narrow cracks or micro-cracks.
With MTC Wesgo Metals' PSP™ technology, low porosity eliminates braze repair shrinkage. The porosity of custom performs is less than 2%, so little or no shrinkage occurs–this is a major advantage of MTC Wesgo Metals' PSPs™ over traditional brazing pastes and green tapes. These braze methods present several problems, primarily with uncontrollable shrinkage and multiple rebrazing cycles. Unlike pastes and green tapes, PSP™ components require minimal post-braze grinding or machining to restore a part to its original dimensions. PSPs™ are available in a flat plate, cut preforms, tapered and curved preforms and a 3-Dimensional bushing, which is used to restore worn holes or bores.
