The present research deals with the study of the effect of Nickel Coating on the fatigue resistance of carburized and uncarburized AISI 301 stainless steel. Six groups of bending fatigue specimens were prepared for fatigue test.
Two groups of the carburized specimens were precoated with Nickel. The Nickel coated specimens were then case carburized at a temperature of (540°C) for 90 minute. The other Nickel coated specimens were then case carburized at a temperature of (950°C) for 120 minute.
Experimental results revealed an increase in fatigue resistance by (25%) for Nickel coated specimens which are carburized at low temperature of (540°C) as compared with the as received specimens.
The surface hardness was increased by 79.4% for those specimens that have been carburized at a temperature of (540°C), while the specimens that have been coated by Nickel then carburized at low temperature of (540°C) showed a 34.3% increase in surface hardness.

Zn–Ni alloy based coatings have high corrosion resistance, good adherence and
unique physical as well as mechanical properties. In the present work, nickel was
dispersed in the under layer of hot dip zinc coating (Galvanizing). showed substantial
improvement in physical as well as galvanic performance. The presence of nickel in the
under layer was found to result in good adherence, less porosity and better hardness .The
presence of nickel decreases the thickness of the coating and enhances the corrosion
resistance character.
