Load effect in abrasive wear mechanism of cast iron with graphite and cementite
(ELSEVIER SCIENCE SA, 2009)
In this study four irons were casted with different chromium and vanadium contents: 2.66% Cr, 5.01% Cr, 2.51% V and 5.19% V. Their microstructure is composed of: ledeburite, graphite and M(3)C carbides (cementite). ...
Tempering temperature effects on abrasive wear of mottled cast iron
(ELSEVIER SCIENCE SA, 2009)
The effects of different tempering temperatures (300-600 degrees C) on abrasive wear resistance of mottled cast iron were studied. Abrasive wear tests were carried out using the rubber-wheel test on quartz sand and the pin ...
Particle size effect on abrasion resistance of mottled cast iron with different retained austenite contents
(ELSEVIER SCIENCE SA, 2009)
Effects of particle abrasive sizes on wear resistance of mottled cast iron with different retained austenite contents were studied. Abrasive wear tests using a pin test on alumina paper were carried out, using abrasive ...
Effect of particle hardness on mild–severe wear transition of hard second phase materials
This study analyzes the effect of particle hardness on the transition from mild to severe abrasive wear. White cast iron with 1.9 wt% Cr with austenitic and martensitic matrices, white cast iron with 13.8 wt% Cr and 24.4 ...
Dry sliding metals process modelling: dynamical system paradigm
(2018-11-13)
The progressive damage and material loss occurring on a component surface as a result of its movement relative to the adjacent working parts has profound economic consequences (substitution costs, inactivity of machines, ...
