The influence of induction hardening on the impact wear resistance of compacted graphite iron (CGI)
Wear, 2011The aim of this work was to study the impact wear resistance of untreated and induction hardened compacted graphite iron (CGI). Testing was carried out on a bespoke impact wear test rig to look at the effect of the material properties, before and after hardening, on the level of wear.

Milling Forces of Compacted Graphite Iron (CGI) and Gray Iron (GI)
Materials Science Forum, 2014Compacted graphite iron (CGI) has excellent comprehensive performance of strength, hardness, abrasion resistance, shock absorption and thermal conductivity as an ideal material for making engine parts. The material performance of CGI is compared with that of gray iron (GI) and spheroidal graphite Iron (SGI). Some research shows that the strong adhesion

Evaluation of Hard Coating Performance in Drilling Compacted Graphite Iron (CGI)
Journal of Materials Engineering and Performance, 2013The aim of this investigation was to compare the performance of the following commercial coatings system, TiAlN/TiN, AlCrN, and TiSiN/AlCrN, deposited in cemented carbide tools in drilling compact graphite iron (CGI). The drilling tests were conducted adopting two cutting speeds: 80 or 150 m/min.

On the Wear of Carbide and Cermet Tools in Machining of Compacted Graphite Iron (CGI)
ASME/STLE 2007 International Joint Tribology Conference, Parts A and B, 2007This work presents an extension of a previous investigation [1] conducted on gaining an understanding of the critical tribological issues encountered in the machining of compacted graphite iron (CGI) using different cutting tool materials. As part of this study, wear tests were conducted on flat-faced coated and uncoated carbide tools and coated and ...

The Study of Mechanical Properties of Degraded Compacted Graphite Iron(CGI) Under 873~1273 K
Journal of the Korean Society for Nondestructive Testing, 2013Compacted graphite iron(CGI), also known as vermicular graphite iron, is a metal which is gaining popularity in applications that require either greater strength, or lower weight than cast iron. Recently compacted graphite iron has been used for diesel engine blocks.
