- Abstract
This paper analyses the contact fatigue behavior of a 40Crl30 coating deposited in electric arc on an 18MnCrll base material. The samples were subjected to contact fatigue on the AMSLER installation in limit and mixed lubrication conditions and analyzed on the LEICA DMI5000 M microscope. A finite element analyses was made on CAD models of the samples to assess the stress distribution. The FEM analyses was done using the ANSYS13 software. From the finite element analyses resulted where and how cracks appear in the sample. The coating had the purpose to improve the contact behavior of c ams from the point of view of wear. The sample with coating subjected to fat iguewearin mixed lubrication conditions had the best behavior.
