Abstract

<span style="mso-ansi-language: EN-US" lang="EN-US">This study discusses the effects of B₄C addition on the morphologies of primary carbides and eutectic colonies in FeW weld-surfacing alloys.<span style="mso-ansi-language:EN-US;mso-fareast-language: ZH-TW" lang="EN-US"> Results reveal that a series of FeW <span style="mso-ansi-language:EN-US" lang="EN-US">weld-surfacing<span style="mso-ansi-language:EN-US;mso-fareast-language:ZH-TW" lang="EN-US"> alloys with different B₄C contents are successfully fabricated onto AISI 1060 steel by using <span style="mso-ansi-language:EN-US; mso-bidi-font-weight:bold" lang="EN-US">tungsten inert gas (TIG) <span style="mso-ansi-language:EN-US;mso-fareast-language:ZH-TW" lang="EN-US">arc welding. <span style="mso-ansi-language:EN-US;mso-bidi-font-weight:bold" lang="EN-US">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 <span style="mso-ansi-language: EN-US" lang="EN-US">depending on the<span style="mso-bidi-font-weight:bold"> rate of B₄C and coating conditions. The maximum microhardness value of the coating is about 1095 HV.<span style="mso-bidi-font-weight:bold">
