- Abstract
This paper presents the contact fatigue wear behavior of a 40Cr130 metallic coating obtained by electric arc deposition. The coating was deposited on an 18MnCr11 steel alloy. Wear is one of the major failure causes for many component parts from an internal combustion engine. The cams of a camshaft are subjected to wear due to the sliding of contact surfaces in an EHD lubrication regime. The samples were tested on the AMSLER installation for a period of 30 hours to fatigue wear in mixed and limit lubrication conditions. To highlight the results obtained after the test electron microscopy was used. For this purpose the QUANTA 200 3D DUAL BEAM microscope installation was used.
