Anodizing

Field Of StudyOverviewAluminiumTypesPropertiesHistoryUsesResearchConstructionUsageTechnologyAnodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.The process is called anodizing because the part to be treated forms the anode electrode of an electrolytic cell.Anodising increases resistance to corrosion and wear,and provides better adhesion for paint primers and glues than bare metal does.Anodic films can also be used for several cosSee more on en.wikipedia Text under CC-BY-SA licenseAluminium alloys are anodized to increase corrosion resistance and to allow dyeing,improved lubrication,or improved adhesion.However,anodizing does not increase the strength of the aluminium object.The anodic layer is insulative.When exposed to air at room temperature,or any other gas containing oxygen,pure aluminium self-passivates by forming a surface layer of amorphous aluminum oxide 2 to 3 nm thick,which provides very effective protection against corrosion.Aluminium alloys typicallSee more on en.wikipedia Text under CC-BY-SA licenseGenerally,hard anodized parts have coatings which exceed 10 m (0.01 mm or 0.00004 inches) with typical coatings exceeding 25 m (0.025 mm or 0.0001 inches).Decorative anodizing usually features coatings of less than 10 m and,although durable,doesn't have the same exceptional wear characteristics of hard anodizing.Decorative or architectural treatments are commonly found on consumer items such as domestic cookware,electronic device casings,and ornaments.See more on wisegeekAnodized aluminum cookware has been around for a long time.It is lightweight and inexpensive.Natively,it is soft,and it does react with acidic foods,becoming toxic.Manufacturers found that aluminum can be anodized to make it stronger,slicker,more durable,and non-reactive with foods.Calphalon,a maker of anodized aluminum cookware explains it this way:See more on yourcookwarehelperThe outer coating is also extremely hard,typically much harder than the original metal.In many cases,a thick hard anodized coating can be as hard as tool steel.It's also very wear resistant,meaning that it is often used for pistons and other sliding parts that often rub together.Because the oxidation layer is part of the metal itself,it won't peel off; the metal surface may be rough after it's anodized,however,so it may be necessary to grind it down to prevent bits from breaking off.Hard anodized metals are usually very insuSee more on wisegeekAnodizing was first used on an industrial scale in 1923 to protect Duralumin seaplane parts from corrosion.This early chromic acidbased process was called the BengoughStuart process and was documented in British defence specification DEF STAN 03-24/3.It is still used today despite its legacy requirements for a complicated voltage cycle now known to be unnecessary.Variations of this process soon evolved,and the first sulfuric acid anodizing process was patented by Gower and O'Brien in 1927.See more on en.wikipedia Text under CC-BY-SA licenseAlthough aluminum is by far the most common metal subjected to hard anodizing,other materials can benefit from the treatment,including tantalum,magnesium,and titanium.In all cases,the treatments lend the parts exceptional wear and corrosion resistance and can be dyed nearly any color.Common uses for hard anodized parts include heavy commercial cook and bakeware,medical prosthetic parts,and automotive components.The military is another large consumer of these products,as most hard anodizSee more on wisegeekSteel and our health was brought to our attention in the 1970s when a Canadian research team linked aluminum with Alzheimers Disease when they found high concentrations of aluminum in the brains of Alzheimers patients.Since then,the research has been scrutinized in a manner similar to the chicken and the egg story.Which came first,the disease or the aluminum?See more on yourcookwarehelperAnodizing a metal part involves putting it into a liquid that is electrically conductive,typically an acid solution,called an electrolyte.Circuits have a positive electrode (cathode) where electrons enter and a negative one (anode) where they leave; in anodizing,the metal part becomes the negative electrode.When an electric current is passed through the solution,the action of the electrons leaving the circuit through the metal part causes a tough,corrosion resistant coating of oxidization to build up.The coatinSee more on wisegeekHard anodized coatings are typically applied to heavy wear industrial parts intended for use in aggressive or highly corrosive applications.These coatings are typically far thicker and harder than decorative ones,and usually lend the parts a durability approaching that of hard faced or case hardened steel.They also penetrate and cover surface imperfections such as fissures better.As with decorative coatings,hard anodized surfaces can be dyed,although,in most cases,they are left as is due to the purely functionalSee more on wisegeekThe process of manufacturing hard anodized parts differs from decorative coatings in several ways.It uses electric currents that are generally higher and electrolyte solutions that are slightly weaker.The temperature of the electrolyte solution is also lower allowing for less distortion of precision parts and better adhesion of the coating.Generally speaking,the anodizing process is also considered to be relatively environmentally friendly and the byproducts are recyclable.See more on wisegeekHard Anodized Steel precision machining Part Fuson Hard Anodized Steel precision machining Part CNC machining custom machined parts cnc machine shop Product description Hard Anodized Steel Machined Part CNC machining Service.Category surface treatment Tags CNC machine shop,cnc precision machining,machine parts manufacturer,miller machineCNC metal precision machining custom anodized aluminum6).Machining capability 30 sets of the most technologically advanced machining CNC milling machines,20 sets of CNC turning machines,25 sets of Multi-Spindle Japan Precision Swiss CNC lathes,and 4 sets of 2D 3D CMM (image measuring instrument) quality control equipment 3 QC staff,enabling CNC Manufacturing to deliver precise parts within China High Precision CNC Machining Anodizing Steel Jun 23,2021·Precision cnc machining parts equipment aluminum spare parts non standard aluminum parts fabrication Material 6000 series Aluminium Temper T4 T5 T6 Size / Thickness General profiles thickness from 0.8 to 5.0mm,length from 3m-6m or customized available;
