| Abstract Scope |
AISI 8620 is generally low carbon steel which is used in many applications such as bearing, camshaft, fastener, gear and so on. These applications require good surface hardness, toughness and wear resistance. Introducing in situ formation of carbide is one of the ways to improve properties
through the tungsten inert gas arcing (TIG) process. Microstructural characterization reveals that the modified surface consists of martensite in lathe form and irregular shapes of precipitates. X-ray diffraction (XRD) shows the presence of the TaC phase formed on a modified surface. Energy dispersive spectroscopy (EDS) mapping shows tantalum and carbide distribution at the precipitate location. The selected area electron diffraction (SAED) pattern confirms that precipitate has a cubic structure. The modified surface has been marked as an increment in hardness as compared to the base metal. |
