English Abstract

In this research, the influence of carburizing process on low carbon steel AISI 1011 on the mechanical characteristics had been studied.

It was found that hardness of this alloy increased for samples treated with carburizing procedure at 950°C for five hours it became 431.65 HV, while the hardness value of untreated specimens was 169.65 HV.

Furthermore, surface roughness of metal increased for specimen treated with carburizing process, and it has become 1.98 µm.

A pin on disk machine was employed for achieved the tests of wear under constant time 30 minutes for five different applied loads 10, 15, 20, 25 and 30 N.

The results illustrate there is an increment in wear rate with increasing the applied load.

The maximum wear rate became (6.2434×10-8 gm/cm) at load 30 N for untreated specimens, while for carburized specimens the wear rate became (4.7638×10-8 gm/cm ) at the same applied load.

Also, it was observed that the wear resistance for carburized specimens higher than untreated samples.
