Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a Zn—Mg alloy-coated steel sheet having high blackening resistance and coating adhesion, the method comprising: 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, wherein the oxide film comprises a metal oxide and the metal oxide comprises silicon oxide (SiO2) and magnesium oxide (MgO), and wherein, when performing the CCVD process, the base steel sheet is maintained within a temperature range of 330° C. to 450° C. 2. The method of claim 1 , wherein the forming of the Zn—Mg coating layer is performed by a physical vapor deposition (PVD) method. 3. The method of claim 1 , wherein in the CCVD process, air and precursor vapor are supplied according to the following ratio: precursor flow rate:air flow rate=0.8:210 to 2.1:210 (L/min).
