CHETANA is a job shop where we do Hard Anodizing as per customer's requirement. We are and ISO 9001 - 2000 company.
Hard Anodizing is an electrolysis process in which the coating is deposited by Alloys of aluminium a layer of aluminium oxide are produced. Hard Anodizing produces thicker and harder coatings from 25 microns to 100 microns. Hard Anodizing is used for technical purposes corrosion and wear resistance.
In many of the application, we can use Hard Anodizing instead of Hard Chromium plating because it is generally cheaper to apply and presents fewer adhesion problems and will give better oil-retention properties than many types of chromium deposition.

Environment : - Hard Anodizing is an environment friendly process, relatively safe. No extra ordinary precautions are needed to ensure worker safety and environmental hazards.
Colour : - Hard Anodizing is typically oxidation of aluminium and its alloys. Controlled oxidation of these alloys determine the colour of the Component.

It offers the following advantages:

Totally uniform thickness on the entire part
Coating thickness that can be controlled in micron tolerances.
Non-poisonous and colorless in nature,eco- friendly process.
Low working cost.
Stability.

Hard anodizing has unique combination of engineering properties and is widely used for :

High surface hardness, 350 VHN to 850 VHN
Very good adhesion to base material.
High corrosion and wear resistance.
Heat dissipation.
Can achieve salt spray resistance in excess of 1000 hours.
Close dimensional control after coating.
Decorative appearance.
Low specific gravity
High mechanical strength.

A few of the advantages of electroless nickel over hard chrome are:
EN plates to within two ten-thousandths of an inch of the required coating thickness, thus eliminating post grinding operations and cost.
Unlike chroming, EN plates by a chemical redox process which provides uniformity to any configuration of substrate, including blind holes, bolt threads, and impellers.
EN high phosphorus (ENHP) corrosion resistance properties far surpass chrome, as ENHP is an amphorus metallic glass and does not have the crystalline structure of chrome. ENHP can withstand 1000 salt spray hours whereas chrome fails within ten hours.
Whereas ENHP offers superior corrosion protection in acidic environments, EN low phosphorus (ENLP) has proven highly resistant in alkaline environments.
EN bonding to the part is far superior to chrome, approximately 100,000 - 200,000 PSI compared to 40,000 - 60,000 PSI for chromes.
EN can be heat-treated to produce hardness values equivalent to hard chrome. In lubricated wear applications, EN is comparable to hard chrome. In non-lubricated wear applications, a duplex coating of ENLP over ENHP and/or selective heat treatment has shown improvements over chrome.
EN has been used extensively in the oil & gas, automotive, and aerospace industries since 1964.
The future of EN will involve the creation of composite chemistries such as Electroless Nickel Boron
