STEEL SHEET BY COATED ALUMINIUM-SILICON ALLOY AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention relates to aluminum-silicon coated steel and a manufacturing method for the same. The method for coating a steel plate using a sputtering process comprises the steps of forming a first coating layer at an oblique angle by coating aluminum-silicon alloy on the steel plate at the first oblique angle; and forming a second coating layer at an oblique angle by coating the aluminum-silicon alloy at the second oblique angle, which has the same size but a different direction as the first oblique angle. The first and second oblique angles are the angle between the vertical elements of a target and a test piece.
