Abstract
Three compositions, (Ni75Si25)-5Cr, (Ni75Si25)-10Cr and (Ni75Si25)-15Cr, have been
cladded onto Ni-based suaperalloy substrate by pre-placing laser cladding process with a 5 kW
continuous wave CO2 laser. Ni75Si25 was also cladded with the same method for comparison. The
process parameters have been optimized to obtain defect free claddings. The microstructure and the
hardness of the cladded layers were characterized by optical microscopy, scanning electron microscopy,
X-ray diffraction and microhardness measurement. The corrosion resistance of the cladded layers was
measured in a sulfuric acid solution.
