Zusammenfassung:The invention discloses an environment-friendly electroplating formula with cobalt-based ternary alloy replacing hard chromium plating and a preparation method thereof. The environment-friendly electroplating formula with the cobalt-based ternary alloy replacing hard chromium plating includes cobaltous sulfate heptahydrate, nickel sulfate hexahydrate, sodium tungstate dihydrate, citric acid monohydrate and sodium lauryl sulfate. By means of the environment-friendly electroplating formula with the cobalt-based ternary alloy replacing hard chromium plating and the preparation method thereof, the problem of environmental pollution caused by hexavalent chromium is solved, and the technical difficulty on the aspects of hardness and bonding force of a plating layer is overcome.
