The microstructure of the alloys were observed via scanning electron microscopy (SEM) using a back-scattered electron imaging detector (BSE), with elemental compositions of the observed phases determined via energy dispersive X-ray spectroscopy (EDS). Image analysis of BSE images was conducted to ascertain area fractions of individual phases.

# In our samples, two phases of cobalt- face centered-cubic (fcc) and hexagonal close-packed (hcp) coexist with fcc as the predominant phase. The major diffraction peaks at 2θ values of 44.35° and 75.95° corresponding to (111) and (220) crystal planes, respectively, can be indexed as fcc-phase metallic cobalt (JCPDS File Card No. 15–0806, a = 3.5447 A˚). 10 Moreover, hcp-phase cobalt could also be detected as peaks corresponding to 41.6, 44.5, 47.6 and 75.8 related to (100), (002), (101) and (110) planes, respectively, (JCPDS File Card No. 01-071-4239, a = 2.506 A˚, c = 4.069 A˚).11

# Additional improvements in the corrosion resistance and mechanical properties (i.e. hardness and wear resistance) of commercial Stellite hardfacing alloys is achieved either by altering the chemical composition with elements such as C, W or Mo [6], [8], [9] or by varying the deposition techniques and/or parameters [10], [11], [12].
