Laser cladding is a process that utilizes either wire or powder coating material, heated by laser beams, to create a molten pool on the surface of the workpiece. The material quickly cools down, creating layers that are metallurgically connected and more resilient coatings created by thermal spraying, while being harmless to health such as hard chromium plating.
Cladding technology advantages of diode lasers
The top-hat beam profile of a diode laser, part of the laser cladding equipment, creates a particularly even molten pool, which provides fine-grained, pore-free and crack-free coatings of the workpieces. Post-processing is thus reduced to a minimum.
Advantages at a glance
- low exposure time and depth of the laser
- metallurgical connection of layer and basic material
- layers are more resistant than thermal spray coatings
- high surface quality and low warpage, with almost no post-processing necessary
- short laser cladding process period, high-energy efficiency
