Laser Cladding of Mg and Nb Alloys for Improved Environmental Resistance.
Abstract
The present status of laser cladding of magnesium and niobium has been surveyed. The potential of cladding zirconium onto magnesium and titanium onto niobium for improving environmental resistance have been discussed. In the present project zironium has been cladded onto magnesium by preplaced powder cladding technique. The laser beam encounters the powder first placed on the substrate. A very thin layer on the top of the substrate melts an results in a cladding of minimum dilution. Corrosion properties of the Zr-clad region was evaluated in a 3.5 percent MaC1 solution at room temperature. Substantial improvement in corrosion resistance has been observed. The structural characterization of the clad region was done by optical and electron microscopy. EDAS analysis has been done to identify the phases observed in electron microscopy. Keywords: Magnesium; Niobium alloys.
