| Abstract: | Comparison of mechanical properties of medium carbon steel AISI 1040 for
vanadium carbide coated (VCC) and boronized conditions has been studied by
means of microhardness, tensile and impact tests. For
the treated steels, the boriding and
vanadizing processes have been carried out in the same conditions, i.e., at a
temperature of 1210 K for 4 h. The thickness of diffusion layer
has been measured as 5 µm and 100 µm for the VCC and
the boronized steels, respectively. In laboratory conditions, the VCC steels
show considerably higher strength and surface hardening with respect to the
untreated and the boronized steels. At the same time, Charpy V-notch
impact tests have also been carried out for the steels with and without surface
hardening. It is concluded that coating is effective
in improving the mechanical performance of AISI 1040 steels. |
