    • Recently, Indian Scientists have developed a unique laser-based clad coating technology (LCCT) that provides improved protection to the boiler parts in thermal power plants.

    What is Laser Cladding

    • Laser cladding, also known as laser metal deposition, is a technique for adding one material to the surface of another. 
    • Procedure:
      • Laser cladding involves the feeding of a stream of metallic powder or wire into a melt pool that is generated by a laser beam as it scans across the target surface, depositing a coating of the chosen material.

    Significance

    • It can enhance the life of boiler parts by 2- 3 times compared to currently used surfacing technologies. 
    • It has been found that this technology is suitable, not only for boiler parts of thermal power plants but also for any engineering application involving high temperature erosive and corrosive environments.
