A method of cold spraying with cryo-milled nano-grained particles

A method (200) of coating a substrate with cryo-milled, nano-grained particles includes forming a face-centered-cubic gamma matrix (202) comprising nickel, cobalt, chromium, tungsten and molybdenum, adding a dispersion strengthening material (204) to the gamma matrix to form a first mixture, cryo-mi...

Zusammenfassung:	A method (200) of coating a substrate with cryo-milled, nano-grained particles includes forming a face-centered-cubic gamma matrix (202) comprising nickel, cobalt, chromium, tungsten and molybdenum, adding a dispersion strengthening material (204) to the gamma matrix to form a first mixture, cryo-milling (206) the first mixture to form a second mixture to form a nano-grained structure, and cold spraying (212) the second mixture onto a substrate to form a coating having a nano-grained structure.
