A study of spur gear pitting formation and life prediction
TL;DR: In this paper, a numerical prediction on pitting formation is carried out in spur gear made from austempered ductile iron, where general two-dimensional rolling sliding contact situations are considered for the development of the analytical model.

A descriptive model of wear evolution in rolling bearings
Idriss El-Thalji,Erkki Jantunen +1 more
TL;DR: In this article, the authors propose a descriptive model of the wear evolution process in rolling bearings over the whole lifetime, which uses a wide range of empirical findings in the literature to describe the wear interactions and evolution in the five-stage scenario: running-in, steadystate, defect initiation, defect propagation, and damage growth.

Machining performance of vegetable oil with phosphonium- and ammonium-based ionic liquids via MQL technique
Amiril Sahab Abdul Sani,Amiril Sahab Abdul Sani,Erween Abd Rahim,Safian Sharif,Hiroyuki Sasahara +4 more
TL;DR: In this article, the advantages of using refined bio-based metalworking fluids (MWFs) with the presence of low toxic, biocompatible and oil-miscible ionic liquids (ILs) additives at nominal weight concentrations of 1, 5 and 10% were explored during orthogonal cutting of AISI 1045 steel.

Austempered ductile iron (ADI) gears : Power loss, pitting and micropitting
TL;DR: In this paper, a systematic experimental evaluation of austempered ductile iron (ADI) as a gear material was performed on the FZG test rig and the results showed that ADI is a material to be considered by gear designers, once the energetic behavior of ADI gears is similar to carburizing gears.

Contact fatigue resistance of austempered and partially chilled ductile irons
Ricardo Dommarco,J.D Salvande +1 more
TL;DR: In this article, the results of laboratory tests carried out to evaluate the rolling contact fatigue (RCF) resistance of ductile iron with different treatments were reported in a flat washer type RCF apparatus, at loading and lubricating conditions leading to the interaction of surface microasperities.

Experimental Investigation on Rolling/Sliding Contact Fatigue Crack Initiation with Artificial Defects
TL;DR: In this paper, the authors investigated the influence of surface roughness, hardness, and temperature on surface crack initiation and found that surface cracks were easily found for film thickness parameters less than 0.3.
Competition between fatigue crack propagation and wear
TL;DR: Based on a semi-empirical derivation of the Paris fatigue law, the fatigue crack length a is related to the yield limit or flow stress, which ultimately is linked to the hardness of the material as mentioned in this paper.
