摘要：
A method for manufacturing a part coated with a protective coating includes: forming a protective coating across all or part of the surface of a part, wherein the part includes a refractory alloy including a niobium matrix containing metal silicide inclusions, wherein the protective coating is formed by a pack carburization method from a cement including: i. a mixture A of (NbxTi1-x)3M3CrSi6 and M0.6Cr0.4Si where M denotes Fe, Co or Ni and x is between 0 and 1, or ii. a mixture B of M′Si, NbSi2 and Nb4M′4Si7 where M′ denotes Fe, Co or Ni.
