What is Aluminium Anodizing and How Does It Work | Anodizing Process Overview

[@chrise202]

Beautifully explained. Not just the "How", but also the WHY for each phase! Thank you

[@robi4387]

Anodising is an electro chemical process It will not chip or peel (but doesn't last forever does it! Anodising does not resist salty water like in my dishwasher or the sea or sea air.) Anodising is carried out in a sulphuric acid bath, a cathode is mounted to the inside Aluminium acts as anode Loaded on carrier racks - Anodising is a highly controlled form of oxidation. There are 5 stages (8 really counting the rinsing!) 1 Cleaning to remove grease in an alkali bath, and rinse 2 Etching with caustic or acid bath, and rinse (called: de-smutting) 3 Anodising - current releases the oxygen which grows the anodised layer out of the surface - this generates a lot of heat and the electrolyte must be cooled to maintain the correct temperature. Time in the bath regulates the thickness. Following this the anodised product is rinsed in de-ionised water to remove all minerals that could produce spotting in the final steps 4 Colouring. The newly created anodised surface is porous! And dies or pigments can be introduced. 5 Sealing. Finally, the pores must be sealed using a nickel acetate.

Why we introduce porous to color the aluminum

I worked for a small company that did anodizing --usually a black color. Sometimes if there was a missed spot o a part, the owner would get out the spray paint and touch it up!

[@timcheou5649]

This is not suppose to happen, why do you guys get spot? Bad water?

[@workingTchr]

@@timcheou5649 I'm not sure. Perhaps the surface that was being held by the clip prevented contact with the anodizing solution.

[@sebastianpinto347]

@@timcheou5649 it's due to air trapped under the aluminum sections while in tank. Jig the sections at a good slope and see.

[@ofonwilliam]

The final thickness becoming 2X that of the base metal after anodizing, is it a standard value Or it varies?

[@rashidmohamed50]

Hi there. Love your work. I have a question regarding aluminum oxide. What chemicals or oxides can reduce aluminum oxide melting point if you heat them together in a crucible in a furnace? I know this auestion is not in par with the video above but I dont have your email address. I will appreciate your feedback

[@maryamhafeez6113]

Cryolite - Na3AlF6 - That's why we use it as an additive in Hall-Beroult process

[@kenw8875]

great content! any Anodizing process that would basically make the substrate Non-Magnetic? in other words, any “Type IV” version that when applied prevents Al-vs-Al interface from conducting electricity?

[@PooleySteen]

Typically, what types of quality control methods of chemical analysis of the bath are used to optimise the process?

[@zunairakhan3714]

They do not use groundwater for this purpose..... do they? 😢 I hope they are first treating the wastewater and then using it for anodising........

[@timcheou5649]

Why do they need to use clean water? For harder finish?

[@mrsoftball4u2nv]

We use well water in our cleaners but RO water in rinses, anodize tanks and seals. This helps eliminate hard water spots due to high iron in well water.
