Paper Abstract

The Surface Laser Alloying (SLA) process using High Power Diode Laser (HPDL) with rectangular beam spot and uniform energy distribution across the spot was investigated. The surface of substrate tool steel was alloyed with cobalt based powder injected directly to the weld pool. The parameters investigated were laser power, traveling speed and powder feeding rate. The results showed that it's possible to produce high quality surface layer alloyed with diode laser. Thickness of the alloyed layer is in a range from 0.7 up to 2.5 mm, and its micro hardness exceeds 1000 HV0.2.
