| Abstract: | This study discusses the effects of B4C addition on the
morphologies of primary carbides and eutectic colonies in FeW weld-surfacing
alloys. Results reveal that a series of FeW weld-surfacing alloys with
different B4C contents are successfully fabricated onto AISI 1060
steel by using tungsten inert gas (TIG) arc welding. SEM
observations show that the obtained coating sheet has a smooth and uniform
surface, as well as a metallurgical combination with the AISI 1060 steel substrate
without cracks and pores at the interface. Fe23(C,B)6, Fe3(C,B),
FeW2B2 and FeW3C boride and carbides are
determined in the microstructure. The microhardness values of the coating
results show a difference depending on the rate of B4C
and coating conditions. The maximum microhardness value of the coating
is about 1095 HV.
