write about anodizing aluminium.
Answers
The Process of coating thick aluminium oxide layer on Iron or other elements is called Anodising. Anodising can prevent Iron from rusting by providing a thick oxide layer on its surface.
HOLA AMIGO!!!
Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish.
Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized.
The anodized coating is hard, durable, will never peel, and, under normal conditions, will never wear through. The purpose of anodizing is to form a layer of aluminum oxide that will protect the aluminum beneath it. The aluminum oxide layer has much higher corrosion and abrasion resistance than aluminum.
