Abstract:
Provided is a method for manufacturing a Zn—Mg alloy-coated steel sheet having high blackening resistance and coating adhesion. In one implementation, the method may include forming a Zn—Mg coating layer on a base steel sheet and performing a combustion chemical vapor deposition (CCVD) process to form an oxide film. The oxide film may include a metal oxide and the metal oxide may include silicon oxide (SiO2) and magnesium oxide (MgO). The base steel sheet may be maintained within a temperature range of 330° C. to 450° C. during the performing of the CCVD process.
