Abstract: The present invention provides an in-situ method for synthesizing a Ni—W—WC composite coating, which includes the following steps: immersing a carbon steel substrate to be coated in an electroplating solution and electroplating, to obtain a Ni—W—C alloy coating on the surface of the carbon steel substrate; and then subjecting the alloy coating to high temperature heat treatment to obtain the Ni—W—WC composite coating. The electroplating solution comprises the following components: a nickel salt, a tungstate, citric acid, a citrate, a recarburizer, and a wetting agent. The present invention shows merits of simple operation, high current efficiency, simple electroplating process, and is clean and causes no pollution, thus meeting the requirements of environment protection.
