The robust magnesium surfaces with multi-functions are highly desirable, and the simple and scalable methods to construct such surfaces are urgently indispensable. Herein, we conducted a one-step spraying method to facilely fabricate the robust coating with multi-functions on magnesium alloys. The as-sprayed magnesium alloys surface is superhydrophobic with a static water contact angle (WCA) of 157.0{\textdegree} and a roll-off angle of 6.0{\textdegree}. Such surface has excellent mechanical, chemical and thermal stabilities, even undergoing various physical and chemical damages, including sand impact (10 g min-1, >=20 min), water impact (2 impacts s-1, >= 180 min), abrasion (1.00 kPa, >=25 cycles), peeling (>=2.15 kPa), high temperature (200{\textdegree}C, >=24 h), strong acidic/salty/basic media (pH = 1\~{}13) and organic-solvent immersion (ethanol and n-hexane, >=24 h), demonstrating brilliant robustness. Notably, the surface displays multi-functions of\ corrosion protection, anti-fouling and\ heat insulation, which will undoubtedly promote the much wider applications of magnesium alloys.
