4. Conclusions
In this research, it is found that the carburized layer thickness
ranges from 25 μm to 64 μm and the surface hardness ranges from
340 HV to 1512 HV. The PC sample exhibits a significant enhancement
in wear behavior, whereby the samples attain the lowest
specific wear rate and wear volume. In conclusion, it is proven that
the surface properties and wear behavior of DSS can be enhanced
appreciably via PC process using fine grain microstructure. It is noteworthy
that the application of an external force in the carburizing
process could produce such a different result.
