Abstract

Provided are a method of metal surface treatment by which material deformation does not occur after surface treatment and there is no limitation in material of an object to be treated, and a solution of metal surface treatment used in the method. The method includes: electrolyzing an object to be treated in a solution obtained by using a composition comprising 30 to 89 parts by weight of NaCN, 1 to 60 parts by weight of KCN, 10 to 69 parts by weight of Na2CO3 or a composition comprising 30 to 60 parts by weight of NaCN and 40 to 70 parts by weight of Na2CO3; maintaining the solution to have temperature of 400°C-800°C and immersing the electrolyzed object to be treated into the solution for 1 to 4 hours; and slowly cooling the immersed object to be treated at the room temperature.
