Presentation Description

Anodizing is an electrolytic process where the surface of the metal oxidised. The oxide formed on the surface works as a shield to the inner metal and protects it from the outer environment.

HTTP://INDACOCOATS.COM/ WHAT IS ANODIZING • ANODIZING IS AN ELECTROLYTIC PROCESS WHERE THE SURFACE OF THE METAL OXIDISED. THE OXIDE FORMED ON THE SURFACE WORKS AS A SHIELD TO THE INNER METAL AND PROTECTS IT FROM THE OUTER ENVIRONMENT. • IN THIS PROCESS THE METAL IS PLACES IN A TANK FULL OF ELECTROLYTE SOLUTION AND A HIGH VOLTAGE CURRENT IS PASSED THROUGH THE TANK. THIS CURRENT OXIDISE THE SURFACE OF THE METAL AND ACT AS SHIELD TO THE METAL. • ALUMINIUM IS THE MAJORLY USED METAL IN ANODIZING. MOST OF THE METAL THAT ARE ANODIZED ARE ALUMINIUM OR ITS ALLOY . MAGNESIUM TITANIUM ZINC ARE OTHER METALS WHICH ARE ANODIZED.

WHERE IT IS USED ANODIZED IS AN INEVITABLE FOR ALMOST ALL THE MANUFACTURING INDUSTRIES. THE KIND OF ADVANTAGE ANODIZING GIVES MAKES IT USEFUL FOR ALL THE METAL BASED MANUFACTURING. ANODIZING IS MOST COMMON FOR IMPROVING CORROSION RESISTANCE ON CERTAIN ALLOYS PARTICULARLY THOSE THAT ARE SUBJECT TO MARINE ENVIRONMENTS – THINGS LIKE SHIP HULLS DOCK COMPONENTS AND OIL RIG STRUCTURES FOR EXAMPLE. ITS ALSO USED FOR ABRASION CONTROL AND IS COMMON IN SANDPAPERS BECAUSE OF ITS HIGH HARDNESS.

slide 5:

• BENEFITS OF ANODIZING DURABILITY: IN ANODIZING THE SURFACE OF THE METAL GET COATED WITH THE NON-METALLIC OXIDE. THIS PREVENTS THE CONTACT OF THE METAL FROM OUTSIDE ENVIRONMENT MAKING IT MORE DURABLE AND STRONG

slide 6:

FINISHING IN THE PROCESS THE METAL GETS ATTRACTIVE FINISHING. SURFACE CAN EITHER GET COLOUR OR CLEAR FINISHING DEPENDING ON THE NEED BUT BOTH LOOKS SHINY AND ATTRACTIVE EASE OF MAINTENANCE SCARS AND WEAR FROM FABRICATION HANDLING INSTALLATION FREQUENT SURFACE DIRT CLEANING AND USAGE ARE VIRTUALLY NON-EXISTENT. RINSING OR MILD SOAP AND WATER CLEANING USUALLY WILL RESTORE AN ANODIZED SURFACE TO ITS ORIGINAL APPEARANCE. MILD ABRASIVE CLEANERS CAN BE USED FOR MORE DIFFICULT DEPOSITS.

slide 7:

COST: OVERALL THE ANODIZING HELPS IN COST CUTTING TO THE BUSINESSES. ONCE THE METAL IS ANODIZED IT HARDLY NEEDS ANY MAINTENANCE. THE LIFE CYCLE OF THE METAL IS INCREASED SO THE REPLACEMENT OF THE METAL MACHINERY OR ANY ANODIZED METAL IS DECREASED. IN THE INITIAL ANODIZING COST BIT MORE THAN PAINT BUT LATER UNLIKE ANODIZING PAINT HAS TO BE DONE AGAIN AND AGAIN FREQUENTLY . SAFETY UNLIKE ANY OTHER COATING ANODIZING IS NOT HARMFUL. SOME ANODIZED METALS ARE USED IN MEDICAL EQUIPMENT AND UTENSILS. YOU WILL GENERALLY FIND ANODIZED PRESSURE COOKER OR FRY PAN IN YOUR HOUSE. THIS IS ONE OF THE GREATEST ADVANTAGE OF ANODIZED THAT IT CAN BE USED IN MANY WAYS
