Coating structure and method for forming the same

摘要

The invention provides a coating structure and a method for forming the same where, by forming an aluminium oxide layer and a silicon dioxide layer between a product to be coated and a coating layer, durability, reliability and anti-corrosion of the coating layer can be improved and furthermore, product yield can also be improved. The coating structure formed on the surface of a product includes an aluminium oxide (Al 2 O 3 ) layer formed on the surface of the product, a silicon dioxide (SiO 2 ) layer formed on the surface of the aluminium oxide (Al 2 O 3 ) layer, and a coating composition layer formed on the silicon dioxide (SiO 2 ) layer.
