Abstract
In this study, the sliding wear of a DIN 18MnCrSiMo6-4 continuous cooling bainitic steel plasma nitrided with a nitrogen rich gas composition was investigated. To evaluate the influence of processing time and temperature on mechanical and microstructural characteristics of nitrided layer, the samples were nitrided at 400, 450, 500 and 550 °C for 3, 6 and 9 h. The produced nitrided layers were characterized concerning the microstructure, phase composition, microhardness and surface roughness. The samples were tested by ball-on-flat reciprocating dry sliding for friction coefficient and wear analysis. The tests were stopped after a given damage criteria involving the rapid growth of the friction coefficients and wear. The correlation of the different treatment parameters and resulting case depths and surface hardness with sliding distance at the time of microcracks formation or delamination of the surface layer was evaluated statistically by the analysis of variance (ANOVA). The plasma nitrided samples at 550 °C showed better wear performances in the ball-on-flat tests than the other groups investigated, since these samples have a thicker compound layer and diffusion zone higher than the other conditions investigated. In general, the beginning wear is slower because of the hardest region of the compound layer.

The tests were performed using a new equipment, built to simulate aqueous erosion and monitor its electrochemical behaviour. This test was called electrochemical slurry erosion wear method. In this equipment, it is possible to measure the effect of simultaneous erosion wear and electrochemical tests on the passive film behaviour. This kind of test on titanium was not found in the literature review, until now. The aim of this study was to analyse the behaviour of the passive titanium oxide layer,...

The effects of hot deformation on the bainitic transformation of a low carbon steel during continuous cooling were comprehensively studied through in situ high-energy synchrotron X-ray diffraction, dilatometry, and ex situ microstructural characterizations. The obtained results indicated that the prior deformation of austenite at 950 °C accelerates the bainite formation at the early stages. During the ongoing of the transformation, both the overall kinetics of bainite and carbon enrichment of au...

Abstract In this study, different configurations of hard micro-patterns on AISI 316LM samples are obtained by a dry etching step followed by plasma nitriding. A “ball-on-plane” tribometer was used for low velocity reciprocal dry friction tests in order to characterise the influence of configurations on asperity lifetime, friction coefficient and wear mechanisms. The distance between asperities plays a key role in friction and wear behaviours by acting on contact pressure and development of debri...

Several process variants of plasma nitriding can be distinguished depending on the location of the voltage introduction. The aim of this study is to compare three different variants of plasma nitriding (DC plasma nitriding, active screen plasma nitriding, and active screening process with bias voltage application) extended by the study of the coverage of active screen on C45E unalloyed steel, using two different N2-H2 gas mixtures. The thickness of the compound layer was measured using a scannin...

Grey cast iron is commonly utilized as an engineering material owing to its some properties such as its good machinability, ability to dampen vibrations, low-stress concentration, high thermal conductivity, good castability and low cost. Especially when this material is used as camshaft material, it can be exposed to wear because of its low wear properties. So, various surface treatment is applied to improve tribological properties of the grey cast iron. In this study, the grey cast irons were p...

Abstract In materials employed in the marine oil extraction, a nitrided layer produced by plasma immersion ion implantation (PI3) can improve the surface resistance against abrasion and still work as a strengthened substructure for deposition of hard coatings. PI3-modified supermartensitic stainless steel (SMSS) surfaces consisted of an iron nitride-rich case followed by N-solid solution; thicknesses of both regions grew as the treatment temperature increased from 300 to 400 °C. The amount of ni...

In this work 300M steel samples is used. This high-strength steel is used in aeronautic and aerospace industry and other structural applications. Initially the 300 M steel sample was submitted to a heat treatment to obtain a bainitic structure. It was heated at 850 °C for 30 minutes and after that, cooled at 300 °C for 60 minutes. Afterwards two types of surface treatments have been employed: (a) using low-power laser CO 2 (125 W) for introducing carbon into the surface and (b) plasma nitriding ...

Abstract Martensitic stainless steel is a potential material class for selection in some tribological systems, particularly those subjected to wear by hard particles and corrosion. To improve its mechanical resistance, without loss of corrosion performance, surface treatments such as low-temperature nitriding and carburizing have been systematically employed. In this context, this paper studied martensitic stainless steel samples subjected to different plasma-assisted treatments, in the case the...
