Abradable composition and method of manufacture

摘要

A thermal spray powder having a first component A mechanically blended with a second component B, wherein the first component A is a metal or metal composite, preferably at least one of Ni—Cr—Al clad ABN, Ni—Cr—Al clad HBN, Ni—Cr—Al clad agglomerated hexagonal boron nitride powder with organic binder, Ni—Cr—Al agglomerated hexagonal boron nitride powder with inorganic binder, an MCrAlY type powder where M is at least one of Ni, Co, Fe, and wherein component B is a polymer clad with at least one of nickel, nickel alloys, nickel chrome alloys, nickel chrome aluminum alloys, nickel aluminum alloys, cobalt and cobalt alloys. The result is a thermal spray powder of four distinctly different phases making the powder a four-phase blend.
