Give 1 advantage ok corrosion |
|
Answer» \tSurface corrosion forms an oxide layer. It acts as a barrier for air and moisture and thereby preventing the inner metal from corrosion.\tSome metals like zinc act as sacrificial anodes to prevent corrosion to other metals.\tGalvanic corrosion is the principle that is used in batteries. Here, two metals carbon and zinc are intentionally mixed together in a electrolyte solution where zinc corrodes faster in order to generate electrical charge. We have no need to break down them by machinary |
