· In this process, the aluminium is connected to a circuit, as shown in Fig. 31.4, where it forms the anode. The solution is prepared so that, rather than removing metal from the anode, the process significantly increases the thickness of the oxide layer, and enhances corrosion resistance. It may also be used to make an attractively coloured ...
Conventional Aluminum Powder Metallurgy Alloys
Atomization is the most widely used process to produce aluminum powder. Aluminum is melted, alloyed, and sprayed through a nozzle to form a stream of very fine particles that are rap- idly cooled--most often by an expanding gas. Atomization of aluminum is discussed in more detail in the article "Production of Aluminum Powders" in this Volume.

Aluminium paints or powder coating | Comhan Aluminium
Before making a choice between painting or powder coating it is important to consider the preparation. Without the correct preparation, painting or powder coating aluminium will not produce the desired result. If you don''t process the material properly there is a chance that the paint won''t adhere well and as such will peel quickly.
How Aluminum is Produced
Pigments & Powder | The Aluminum Association
Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders.PM processes can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs.. Powder metallurgy is also used to make unique materials impossible to get from melting or ...
