2.3. Microstructure analysis
Optical (OM) and scanning electron microscopes (SEM)
were used to analyze the microstructure of the specimens.
Secondary electron imaging allowed morphologic description
of the worn surfaces, while backscattered electron imaging and EDS compositional maps were used to qualitatively
describe chemical variations in the microstructure. Cross sections
of the weld were polished and etched with Kalling’s
(hardfacings 2 and 3) and Nital 2% (hardfacing 1). Different types of carbides present in the microstructures were first
identified on the basis of their morphologies and confirmed
by micro-hardness measurements.
