The methodology non–destructive test inspection by ultrasound for predict the beginning of the failure of a material subject to rolling contact fatigue
(Universidad de Carabobo, 2015-04)
The methodology of inspection of the non-destructive testing by means of ultrasound was proposed and implemented to predict the beginning of the failure of an element under rolling contact fatigue, since it is not counted ...
Rolling contact fatigue resistance of ductile iron with different nodule counts and matrix microstructures
(Elsevier Science Sa, 2006-07)
Thin wall ductile iron castings are being used in the industry as a way to improve the strength to weight ratio of machine parts. The high cooling rate, suffered by thin wall parts during the solidification process, promotes ...
Rolling Contact Fatigue Resistance of Cryogenically Treated AISI 440C Steel
(Springer, 2020-04-20)
AISI 440C is a high carbon martensitic stainless steel, primarily used in bearing applications. For this study, one group of AISI 440C steel disks was quenched in oil and tempered. Another group was soaked in liquid nitrogen ...
Optimization of the rolling contact fatigue (RCF) performance of carbidic austempered ductile iron (CADI)
(Elsevier, 2020-03)
Austempered ductile iron (ADI) has a good combination of mechanical properties and castability allowing it to replace forged steels while offering lower costs. CADI is thought to improve ADI's abrasion resistance by the ...
Rolling contact fatigue resistance of Carbidic Austempered Ductile Iron (CADI)
(Elsevier Science SA, 2019-01)
The austempered ductile iron (ADI) with carbides in its microstructure, commonly known as CADI, is a relatively new variant of ductile iron intended to resist abrasive wear in different tribosystems by selecting the ...
Rolling contact fatigue behavior of Ti/TiN coated ADI by cathodic arc deposition
(Elsevier, 2016-12-13)
This work studies the rolling contact fatigue (RCF) behavior of austempered ductile iron samples coated with Ti/TiN by cathodic arc deposition. The influence of the TiN layer thickness on the characteristics and RCF life ...
Liquid transfer from single cavities to rotating rolls
(Cambridge University Press, 2014-05)
In this work we study computationally the dynamics of a liquid bridge formed between a 2D trapezoidal cavity, which represents an axisymmetric cell or a plane groove engraved in a roll, and a moving plate. The flow is a ...
Rolling contact fatigue behavior of dual-phase austempered ductile iron
(Elsevier Science Sa, 2019-01)
In this work the rolling contact fatigue (RCF) behavior of dual-phase austempered ductile iron (ADI) was studied and compared to that of conventional ADI. The effect of surface finishing (manual vs. automatic grinding) on ...
Rolling contact fatigue resistance of PVD CrN and TiN coated austempered ductile iron
(Elsevier Science Sa, 2013-09-21)
This work studies the rolling contact fatigue (RCF) behavior of PVD CrN and TiN coated ADI samples. The effect of the substrate surface finishing method (grinding and polishing) and coating material on RCF life is also ...
