TECHNOLOGY
LFT’s new Laser Assisted Cold Spray technology delivers more productivity by enhancing the deposition of a supersonic stream of metal powder by using localised laser heating.
The surface deformation of the material allows for an efficient bonding without reaching melting temperature, preserving the materials integrity from undesirable transformations and without the use of expensive carrier gases.

Cold spray is a promising technology for enhancing manufacturing sustainability:
✅ It does not require the melting of powder particles. This minimizes oxidation and undesirable phase transformations.
✅ It can be run at a low energy and gas consumption for a high deposition rate.
✅ It can provide a cost-effective solution to the restoration of expensive components that would otherwise be scrapped. This can provide a sustainable solution for the recovery of obsolete niche retrofits.
✅ Laser assistance can expand cold spray to a variety of new materials and enable the deposition of thicker coatings at a low running cost.
Laser assisted cold spray can overcome the challenges of coating thick layers of tungsten:
✅ It significantly increases deposition efficiency while using a low-cost carrier gas.
✅ It can expand Cold Spray capabilities to the deposition of refractory materials at a high deposition rate.
Our Laser Assisted Cold Spray technology has enabled the deposition of thick Tungsten coatings of up to 2.5mm.
