Abstract
Laser cladding is a technique to produce high quality coatings that can be applied in several fields of industry. It makes possible the use of a vast variety of deposition materials, even ceramics, while still increasing productivity when related to other processes. The advantage of using wire as feedstock material instead of powder is the known higher productivity, the reduced material wastage and the possibility to have a cleaner process environment. Thus, the purpose of this study is to investigate the laser cladding process with a high power Ytterbium Fiber laser, while using Inconel® 625 wire as feedstock material. Through varying process parameters, as speed rate, focal adjustment and laser power output, the research aimed to obtain low dilution associated with high productivity results in order to validate the cladding process over a flat substrate. Scanning electron microscopy with energy dispersive X-ray spectroscopy, optical microscopy and microhardness techniques were used to characterize the material and were obtained as a result optimized productivity, low dilution and layer consistency. Wire laser cladding with Inconel® 625 demonstrated itself as a promising process to be applied in flat or, in coming works, curved surfaces.
