CRTDH

M/s. Hytronics Enterprise, Hyderabad manufactures phosphor bronze pins (1000 numbers per day) for use as VITAL relays and railway signaling system

Hytronics is looking for a quick and low cost process to replace their existing electrochrome coating process.
The coating should improve corrosion resistance and should not impair electrical conductivity.
24 number of phosphor bronze pins were provided by Hytronics for coating with graphene.
Graphene coating was done by Electrophoretic deposition and sent to Hytronics

Present Status

Although coatings were smooth & homogeneous, it did not satisfy the electrical conductivity requirement as we have used siloxane as post treatment to improve adhesion.
Efforts are underway to coat another 2-D material Mxene that has very high electrical conductivity

The CRTDH was set-up in February, 2019 at CSIR-IMMT. The foundation stone of the CRTDH building along with the Incubator office space was laid by the Director General of CSIR on 1.2.2019. We are working with a vision to take this CRTDH scheme forward in this region and establish supporting linkages with all stakeholders.
