COATING STRUCTURE AND FORMING METHOD FOR THE SAME

摘要

PURPOSE: A coating structure and a forming method thereof are provided to improve durability and corrosion resistance of a coating layer and to improve the yield of a product by forming an aluminum oxide layer and a silicon dioxide layer between a coating target product and the coating layer. CONSTITUTION: A coating structure(100) comprises an aluminum oxide(Al2O3) layer, a silicon dioxide(SiO2) layer, and a coating composite layer. The aluminum oxide layer is formed to the surface of a product. The silicon dioxide layer is formed on the aluminum oxide layer. The coating composite layer is formed on the silicon dioxide layer.
