    Basic Information

Technology developed: Micro Arc Oxidation Coating Technology (TP19768438968)
Category: Technology Service/Know how
Details of Inventor(s):
Inventor Institution/Organization/Company Department Designation
Dr. D Srinivas Rao International Advanced Research Centre for Powder Metallurgy and New Materials Centre for Engineered Coatings Scientist G
Technical Application Area: Engineering
If 'Other', please specify:
Please give more details of new technical application area:
Micro Arc Oxidation (MAO) also known as Plasma Electrolytic Oxidation (PEO) is an electrochemical and electro thermal oxidation in an alkaline electrolyte where the surface oxidation is driven by the supply of high voltage (up to 600 V) pulsed AC power. MAO is a novel and environmental friendly way of creating dense, ultra hard (peak hardness up to 1800 HV) ceramic composite coatings for enhancing the wear, corrosion, electrical and thermal protection of Al alloys.
Organization(s):
International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI) Hyderabad
Affiliated Ministry: DST, Govt. of India
Type of technology development: Indigenous
Does the technology help in replacing any import items currently
procured from outside India?
Yes
Does the technology have export potential? Yes
Category of Technology developed: Immediate Deployment
Stage of Development: Commercialized
Please describe in detail including the TRL Level:
Technology Status: Prototype models of academic and industry scale systems were already fabricated, tested and demonstrated on a variety of applications, installed at customer locations. Application development for various industry segments is currently in progress to promote more technology transfers to the Indian industries and universities. Through rigorous R&D activities pursued over last 2 decades, ARCI has mastered over the MAO process including the equipment design, building, testing, supply, installation and commissioning of academic scale, lab scale and industry scale systems with custom built capacities and capabilities. TRL Level: 09 (Initiate Technology Transfer)

    Abstract:

Applications: Taking advantage of enhanced fatigue strength in addition to the wear, corrosion, thermal and electrical protection, numerous applications ranging from automotive, aerospace, electrical, electronics, wire drawing and textile industry are the potential segments TP19768438968-app.pdf
Advantages: Eco-friendly and economically viable Custom-built technology systems are available in large power supply ranges between 50 to 500 kVA Coating composition can be refined by adding additives to the electrolyte depending upon the requirements of various components 5-40 times life enhancement Easy-to-coat difficult to access regions TP19768438968-adv.pdf

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
