A solution system for removing titanium carbide coatings on substrate surface by two electrolysis steps is provided. The solution system includes a first electrolyte solution for a first electrolysis step and a second electrolyte solution for a second electrolysis step. The first electrolyte solution contains 2-80 g/L soluble alkali metal hydroxide and 5-100 g/L complexant capable of complexing with titanium ions. The second electrolyte solution contains 50-300 g/L soluble alkali metal hydroxide, 5-100 g/L complexant capable of complexing with titanium ions, and 10-60 g/L alkylol amine. The method for removing titanium carbide coating from the substrate mainly includes two electrolysis steps respectively using the first and second electrolyte solution.
