Technology: Other surface modification technologiesLaser cladding process (TOCALO Laser Clad)
TOCALO Laser Clad (TLC) is an overlay technology that forms an overlay layer by injecting a powdered material and uses a laser beam as a heat source to melt and bond the material to the base material surface.

Major features
- Low heat input to the base material
- Minimal heat strains and heat-affected zones
- Minimal base material dilution into the coating
- Easy control of coating thickness
Representative laser cladding coating
TXR7 is a laser cladding coating with excellent wear resistance, exhibiting Suga abrasion test results of wear resistance 5.7 times of SS400 and 3.1 times of SUS304.

Example of laser cladding application
Optimizing the processing conditions to take advantage of laser cladding technology makes it possible to form an overlay coating even on base materials with low-heat capacity surfaces, such as punching metal.
