Wood, metal, and fabric all have different life expectancies depending on their quality. However, it is a fact that they will eventually break down. They can rot, decay, and rust. They eventually need to be replaced, which can lead to high costs. Cost reduction is an essential part of business success. This is why there are always new innovations that improve the durability and life expectancy of products and materials. Anodizing is one example of such an innovation. But what exactly is anodizing? To help you understand anodizing, here is a quick introduction.
The Definition
Anodizing uses electrochemistry to harden and thicken the oxide layer that covers metal. This creates a protective, porous anodic coating that is more durable than any other material except diamonds. Aluminum is anodized most often because it is naturally suitable for the process. However, other metals can undergo anodizing and reap the benefits.
The Process
How does anodizing work? This is the actual boosting of a reaction which occurs in real life without interference. This is how it works:
- An anodizing tank has a cathode in it.
- The tank is filled up with an acid electrolyte solution.
- The bath will be filled with the metal.
- The electrolyte bath’s oxygen ions interact with the metal’s surface ions.
- It is called oxidation.
The Benefits
Industries like the automotive industry value anodizing for its many benefits. Corrosion resistance is one such benefit. Another benefit is increased durability. Anodizing is easy to maintain and retains color better when paint is applied. Anodizing is also non-toxic to the human body and can be done at a lower cost than traditional methods.
Anodizing, which strengthens materials used in final products, is crucial to meeting quality standards and satisfying customers’ demands. Anodizing is a great way to improve the product’s reputation.
