Qualification of the damage induced by friction using X-ray Diffractometry
TypeCommunications sans actes
In a previous study, the capability of X-ray diffraction technique to qualify damage occurring during friction had been proven . The purpose of this study is to complete this research in order to develop a method to quantify the damage induced by the friction loading.

FABRE, Agnès; JEGOU, Sébastien; BARRALLIER, Laurent (2014)Le rodage est un phénomène présent lors des premiers cycles de frottement qui modifie la surface de contact d’une pièce d’un point de vue géométrique, couplé à des modifications de propriétés mécaniques. Le rodage génère ...
A Thermodynamic and experimental study of low-alloy steels after carbonitriding in a low-pressure atmosphere MARRAY, Tarek; JACQUET, Philippe; MANSORI, Mohammed; FABRE, Agnès; BARRALLIER, Laurent (Springer, 2014)The effect of the composition of two steels (B and 6MnCr5) on precipitation of undesirable phases (carbides, nitrides and carbonitrides) under thermochemical treatment (low-pressure or vacuum carbonitriding) is investigated. ...
FABRE, Agnès; EVANS, H-P; BARRALLIER, Laurent; SHARIF, K.J; DESVIGNES, Marc (Elsevier, 2013)Micropitting is a form of surface fatigue damage that occurs in the gear teeth. It is due to the effect of variation in the mechanical loading in the contact zone between the two teeth, induced especially by flank roughness. ...
WEIL, Hadrien; JEGOU, Sébastien; BARRALLIER, Laurent; COURLEUX, Alice; BECK, G. (2016)The present study aims to develop an algorithm able to predict the fatigue lifetime of nitrided steels. Linear multi-axial fatigue criteria are used to take into account the gradients of mechanical properties provided by ...
