The material used in this study was low-alloy steel ESKY- It was shown that radio frequency plasma nitriding of stainless LOS6959. Its chemical composition is summarized in Table 1. steel in combination with a pre-treatment by high pressure torsion Mechanical properties evaluated through tension test are the fol- results in an enhanced Coatings Free Full-Text Torsional Fretting Wear Thus, it is valuable to explore the fretting wear behavior of Ti 3 SiC 2 coatings with oxidation treatment for a further improvement of their tribological properties. For this paper, plasma-sprayed Ti 3 SiC 2 coatings were thermal oxidation-treated at 200, 300, and 400 °C for various durations to improve the fretting wear properties.

Fretting behaviors of a steel up to very high cycle

Abstract In the present work, the fretting fatigue behaviors of GCr15 steel (Chinese GB/T-standard) have been studied up to the very high cycle fatigue (VHCF) regime by using an ultrasonic fatigue system. The main aims of the investigations were the analyses of SN curves, worn morphology, as well as fracture morphology. As expected, the results of the fretting fatigue tests show a reduction Impact and Sliding Wear Properties of Single Layer Current paper handles the comparison of impact wear and sliding wear properties of the hard PVD single layer TiN and Ti(C,N), multilayer (Ti,Al)N and nanocomposite FiVIc® coatings on the plasma nitrided low-alloy 42CrMo4 steel. All the studied coatings demonstrated a relatively high impact wear resistance at the low (104) and medium (105) number of impacts, however, all the studied coatings Materials Special Issue :Tribology:Friction and Wear The evolution of fretting wear behavior and damage mechanism in Alloy 690TT with cycle number was investigated via laser scanning confocal microscopy (LSCM), scanning electron microscopy (SEM), focus ion beam (FIB), and transmission electron microscopy (TEM). The results showed that the fretting running [] Read more.

Wear Behavior of a Low-Alloy (AISI-SAE) 4140 Steel After

Jan 01, 2016 · The behavior of 42CD4 steel (AISI-SAE4140) to the various influential parameters such as load, stress, and exposure time was studied in this context. The present work is to study the effect of some parameters on the wear behavior by fretting wear of 42CD4 steel (42CrMo4) after different heat treatments and particularly the loss of mass as a
