English Abstract

In this paper, study the effect of fatigue behavior on AISI 1039 medium carbon steel electroplated with hard chromium in which the electro deposition method was carried out within a period of 10, 15, 20, 25, 30 minutes plating time, As shot peening were used in this work as a type of surface treatment in which peening was carried out with steel balls for a period of 10 minutes.

It was found that the highest fatigue limit was 300 MPa in case of 10 minutes chromium plated shot peened steel , also it was observed there is reduction in fatigue limit with increasing in time of electroplating.

Coating thickness increases as coating time increasing and this leading to lower the fatigue limit, where the highest coating thickness value was 33µm with 30 minutes coating time and fatigue limit is reduced till 250 MPa.

Also it was found that the coating thickness causes an increase in surface hardness of the alloy.

While as coating thickness increased the surface roughness decreased.
