Nitriding effect on fatigue resistance of grey and nodular cast irons

International Heat Treatment and Surface Engineering, 2012
AbstractThe influence of nitriding on the fatigue resistance of grey and nodular (ductile) cast iron piston rings was studied for six chemical compositions. The selected materials include three grey cast irons: one with a mixed initial microstructure (martensite plus bainite), the second martensitic and another martensitic alloyed with niobium; and ...

DLC deposited onto nitrided grey and nodular cast iron substrates: An unexpected tribological behaviour

Tribology International, 2018
Abstract In the pursuit of suitable alternative substrate materials for DLC coatings, grey cast iron (GCI) and nodular cast iron (NCI) stand out due their vast industrial applications, consequence of its sufficient mechanical strength associated with low cost.

A preliminary investigation of strength models for degenerate graphite clusters in grey cast iron

Procedia Structural Integrity, 2017
Defects morphology primarily affects the mechanical properties of grey cast iron. In large castings, porosity and clusters of degenerate graphite are heterogeneously dispersed into the ferrous matrix and serve as initiation sites for fatigue and fracture

Eutectic cell and nodule count in grey and nodular cast irons

Materials Science and Technology, 2007
In the present work the predictions of a proposed analytical theory were compared with the experimental outcome on metallographic determinations of eutectic cell count N and nodule count Nn. Accordingly, processing of flake graphite and ductile cast irons was carried out under various inoculation conditions in order to achieve a range of ...

On the Roughening of Grey and Nodular-graphite Cast Irons during Surface Melting

Cast Metals, 1988
The gas tungsten arc (GTA) welding process has been used to melt the surface on a series of grey and nodular-graphite iron castings.
