A Study of the Mechanisms and Kinetics of the Localized Corrosion Aggravation of Ductile Iron in a Harsh Water Quality Environment

Metals, 2022
Ductile iron is a high-strength cast iron material. The spherical graphite obtained by inoculation treatment effectively improves the mechanical properties of cast iron, resulting in higher strength than carbon steel.

Characterization of the high temperature oxidation behavior of iron based alloys used as exhaust manifolds

MATEC Web of Conferences, 2018
Nowadays engine capacities of vehicles spread in a wide range due to different vehicle power demands. Power density of engines affects exhaust gas and therefore exhaust gas temperature varies from 650 °C to 1000 °C in exhaust manifolds.

PRODUCTION OF DUCTILE CAST IRON BY RECYCLING GRAY CAST IRON SCRAP WITH ADDING VARIOUS LOCAL MATERIALS

Journal of Engineering and Sustainable Development, 2023
Ductile cast iron is also called spheroidal graphite cast iron or nodular cast iron. It contains graphite in the semblance of nodules. Automobile scrap (i.e., the engine block) made from gray cast iron was used in this study.

Pin-On-Disc Characterization of Brass/Ferritic and Pearlitic Ductile Iron Rubbing Pair

High Temperature Materials and Processes, 2011
Wear behaviour of special brass produced through two different methods (centrifugal and sand casting) was investigated. The wear tests were carried out at sliding velocities of 0.2 ms–1, 0.3 ms–1, 0.4 ms–1 and 0.5 ms–1 and under 10 N, 20 N, and 40 N ...

Corrosion Inhibiting Mechanism of Nitrite Ion on the Passivation of Carbon Steel and Ductile Cast Iron for Nuclear Power Plants

Advances in Materials Science and Engineering, 2015
While NaNO2 addition can greatly inhibit the corrosion of carbon steel and ductile cast iron, in order to improve the similar corrosion resistance, ca. 100 times more NaNO2 addition is needed for ductile cast iron compared to carbon steel.
