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. 种用冷冻研磨纳米粒状颗粒涂覆基材的方法(200)包括形成包含镍、钴、铬、钨和钼的面心立方γ基质(202)，向γ基质加入分散强化物质(204)以形成第混合物，冷冻研磨第混合物(206)以形成第二混合物，从而形成纳米粒状结构，并将第二混合物冷喷到基材上(212)，以形成具有纳米粒状结构的涂层。
