• Indian Scientists have developed a unique laser-based clad coating technology (LCCT) that provides improved protection to the boiler parts in thermal power plants.
• It can enhance the life of boiler parts by 2- 3 times compared to currently use surfacing technologies.

Laser Cladding

• Laser cladding is a technique for fusing a coating material on a substrate.
• It allows materials to be deposited accurately, selectively, and with minimal heat input into the underlying substrate.
• This process allows for property improvements of the surface of a part, including better wear resistance, thus allowing for the repair of damaged or worn surfaces.
• The LCCT has been developed with a meticulous fusing of a Nickel-based soft matrix with hard metallic carbide particles of (tungsten, chromium, or vanadium) on steel parts by employing a high-power laser integrated into a multi-axis robot with process monitoring and control.
