High Power Diode Lasers (HPDL) are the latest developments of laser equipment suitable for laser materials processing, including hardening, cladding and welding operations. A research project entitled “High power diode laser HPDL in coating and surface treatment” was performed in during 2000-2002 as a TEKES and industry funded project and as a part of the TUKEVA Programme. In the project a 6 kW HPDL system was installed in Laser Application Laboratory (LAL) of Tampere University of Technology. The HPDL equipment was used to study high-rate laser coating and hardening processes. The coatings manufactured by HPDL coating were thoroughly characterised and evaluated with their technical properties. HPDL coating was found to be a highly potential surface coating and hardening process for future industrial manufacturing.
