Question

what is anodising?what are it's uses

Answer 1

An anodising is a coat (a metal, especially aluminium) with a protective oxide layer by an electrolytic process in which the metal forms the anode.

ADVANTAGES OF ANODISING

Amongst metals widely used in manufacturing, anodising is unique to aluminium and enhances the surface of the aluminium. The 15 key advantages of anodised aluminium are as follows:

Natural metallic sheen and aspectExcellent corrosion resistanceOver 30 years of proven long term on-site performanceNo risk of adhesion failure of the anodic filmNo risk of fadingNo risk of chalkingNo risk of filiform corrosionPreservation of the original surface texture and designOptimal surface coverageAnodic film is totally impermeableExceptional abrasion resistanceOn-site quality control possible without creating surface damage in testing100% recyclableProduction process can be carried out in accordance with latest environmental standardsLifetime Guarantee available.

Answer 2

Answer:

itis a process of forming a thick oxide layer on the surface of aluminium aluminium develop a thin layer of oxide when left in air this oxide layer is protective and prevent the metal from for the oxidation this layer can be made more thick by anodizing the process clean aluminium article is taken as anode and H2 s o4 as an electrolyte when electric current is passed O2 gas get liberated which react with metal aluminium to form a thick layer of oxide on its surface
