In this blog, we will analyze what is Anodizing and Chrome Plating Aluminium. Their key differences, benefits, and which one to choose.

What is Anodizing?

Anodizing transforms the metal surfaces into strong, decorative, corrosion resistant and anodic oxide surfaces through an electrochemical process. Non-ferrous metals, including titanium and magnesium, are able to be anodized, but aluminum works best for this process. Moreover, aluminum substrate produces anodic oxide that is completely aluminum oxide. 

This aluminum oxide combines with the available metal substrate, and it does not stick to the surfaces with paint or any plate. It makes the chipping and peeling resistive. Furthermore, it has an organized structure containing pores which allow it to work for more processes. Such as sealing and coloring are the main ones. One can anodize the aluminum by dipping it into the acid bath of electrolyte and running an electric current throughout the tank. 

Aluminum works as the anode when the anodizing tank becomes mount with the cathode. In this way, the electrolyte releases oxygen ions and combines with the aluminum atoms. These atoms are present on the surface of the aluminum in the anodizing process. Hence, anodizing is the improvement of the natural elements with the help of oxidation. 

What Is Chrome Plating?

When a thin layer of chromium metal applies to the surface of another metal, it is the process of chromium plating. The metal in the process has glossy details and a hard surface, which is easy to protect through chromium plating. It keeps the metal surface safe from rust and other types of damage. Chrome plating enhances the visual representation of the metal’s surface, and it makes it a good option for decoration and a useful alternative. 

Although it can be an expensive option, it also consumes time in front of other processes like anodizing. In actuality, chrome plating needs special products to clean. Otherwise, it may get stains and discolor over a period of time. 

Chrome plating is common to use for many appealing reasons. It works for the enhancement of resistance and stiffness of corrosion. Moreover, it becomes an ideal option for industrial purposes where wear and tear are a common problem. Hard plating by chrome is another main type of plating that performs well to retain the damage to the components. Also, this type of plating works best for car trim and steel furniture. It is also best for nickel plating. 

Difference Between Anodizing And Chrome Plating

Various Processing Techniques

In electroplating, the metal that has been electroplated, or anode, is the same as the cathode. The type of electrolyte having metal ions for electroplating is a positive current. It is an input between the anode and the cathode. The item that needs plating and the utilization of the material for plating are quite different things. For example, nickel works as the substrate and plating layer in the process or nickel-plating and beryllium copper. 

In anodization, chemical or electrochemical works well to treat the metal. This way, it produces a thin film coating on the surface. A thin coating will develop on the treated material’s surface when electricity passes through a certain electrolyte to the anode. Its further acts as the processed material. If the aluminum alloy oxidizes, an aluminum oxide layer will form on the workpiece’s surface. Aluminum has the ability to dye colors and is chemically stable, resistant to oxidation and acid damage.

A Variety of Processing Objects

Metal or non-metal materials work perfectly to make the majority of platings. The most widely common plating metals are nickel, chromium, tin, copper, silver, and gold. A phrase typically is accurate to describe gold, chromium, and nickel plating, among other platings.

A method for treating a metal’s surface is anodizing. The majority of metals include stainless steel, aluminum alloys, zinc alloys, copper alloys, aluminum alloys, and magnesium alloys. Also, titanium alloys can undergo the anodizing process using the right electrolyte.

Many Processing Philosophies

The main ingredient in electroplating is the cathode. The substance on which the anodizing is going on is the anode. Electroplating happens as a result of the charge effect, which works when metal anode ions move to the cathode and deposit their electrons there. Then right at the moment, the metal in the anode dissolves, and the supply of metal ions in the electrolyte continuously goes on.

Electrochemical techniques work in anodizing to control the formation of oxide layers on aluminum alloys that are easy to oxidize. Improve the mechanical properties of the surface and stop further oxidation of the metal. The most common and efficient technology right now is anodizing. Anodizing can increase the surface hardness and wear resistance of an aluminum alloy.

Different Processing Objects

Many companies make the bulk of plating from metal or non-metal elements. These metals include copper, nickel, tin, chromium, silver, and gold. 

Anodizing is a technique for altering the surface of a metal. Stainless steel, zinc alloys, aluminum alloys, magnesium alloys, copper alloys, and titanium alloys. Also, most other metals are good to anodize with the proper electrolyte.

  1.     How do you distinguish whether the surface is anodized?

In contrast to the glossy appearance of raw metals, anodizing creates a protective oxide layer on a metal’s surface. This is easily recognizable by its unique color and matte finish.

  1.     Does anodizing vs chrome plating enhance surface quality? 

Anodizing can improve the metal’s surface polish, mostly by depositing a protective layer of aluminum oxide on an aluminum substrate. Chrome plating also works to metal effective for the application.

  1.     How much is the color retention of anodizing metal? 

With proper care and maintenance, the anodizing color on a surface can remain for a long time. Although, its durability depends on factors including the type of metal and atmosphere.

  1.     Does anodizing cause surface rusting? 

Rust does not come on by anodizing; rather, it gets slow by the formation of a protective oxide coating on the metal’s surface. The metal gets protection from rust through this layer of resistance to corrosion.
