ABRASIVE TIP BLADE MANUFACTURE METHODS

摘要

In a method for manufacturing a blade, the blade comprises: an airfoil (100) having a root end and a tip (106); a metallic substrate (102) along at least a portion of the airfoil; and a tip coating (152) comprising an oxide abrasive (156) and an aluminum-based matrix (154). The method comprises simultaneous thermal spray of the matrix and the abrasive.
