Titel
Cladding of valves with Co2 laser radiation
Abstract
For the cladding of valves the correlation between the processing parameters laser power, feed rate, beam geometry, powder feeding rate, type of powder and processing results such as layer geometry, clad structure, dilution of clad and base material is presented. The specific problems as influence of heat conduction on the clad tack as well as the optimization of the overlap zone by ramping the laser output power are investigates and discussed.
