    Basic Information

Technology developed: Repair and Refurbishment of Pressure Die Casting Components Using Laser Cladding (TP19761175494)
Category: Technology Service/Know how
Details of Inventor(s):
Inventor Institution/Organization/Company Department Designation
Dr. Ravi Bathe International Advanced Research Centre for Powder Metallurgy and New Materials Centre for Laser Processing of Materials Scientist F
Technical Application Area: Manufacturing
If 'Other', please specify:
Please give more details of new technical application area:
Enhancing service life by surface treatment and recovering component after post damage could have significant economic benefits. Die tool costs 10 percent of cast part. Repair and refurbishment are increasingly common practices, seeking to maximize unit lifetime, availability and profitability. During hot forming of aluminium alloys, dies made up of hot work tool steels get exposed to severe operating conditions that cause significant thermal and mechanical fatigue, high pressure and high hot erosion from flowing molten alloy and result into surface damages like heat checks, erosion and chemical attack in prime locations, limiting or diminishing the service life of the tools. Laser cladding has been successfully used to repair the damaged dies and put to re-use.

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.
