“…Furthermore, the corrosion intensity increases with the laser fluence. A similar correlation between a reduction in the pitting corrosion and surface roughness and microcracks and thus an increase in the current density, has also been observed by Krawczyk et al [22].…”

This paper presents an analysis of the impact of the laser annealing process on the wear resistance and corrosion properties of one of the most commonly used AISI 316 (EN 1.4401) stainless steels. The samples were irradiated using a common available fiber laser (Yb:glass) system in an ambient environment. Considering that laser radiation changes the morphology and physicochemical structure of the surface layer, as well as the mechanical properties, extensive research has been conducted. Electrochemical tests, accelerated corrosion tests in neutral salt spray, x-ray photoelectron spectroscopy chemical analysis, microscopic examination, roughness, as well as friction and wear, were carried out. This study has shown that by properly controlling the energy density of laser radiation, the corrosion resistance of the material can be significantly improved. It has also shown that layers coated with laserinduced oxides are more resistant to wear than the reference samples.

“…The use of a nanosecond laser to modify the surface layer of AISI 304 steel resulted in a smoother surface compared to the reference sample (Figure 4). Smoothing the surface after nanosecond irradiation was also observed by Alwan et al [12], Ruzankina et al [13], and Krawczyk et al [14]. The use of a femtosecond source did not significantly change the surface roughness despite the formation of LIPSS on the surface.…”

This article is aimed to study the effect of laser treatment of AISI 304 stainless steel on the corrosion resistance and chemical composition of the surface layer. The samples were irradiated using two quite different laser sources: IPG Yb:glass fibre laser (τ = 230 ns, λ = 1062 nm) and Trumpf TruMicro Series 2020 fiber laser (τ = 260 fs–20 ps, λ = 1030 nm) that is, in both the long and ultra-short pulse duration regime. It allowed the observation of completely different microstructures and chemical composition of the surface layer. In this study, the morphology of the samples was accessed using both Keyence digital microscope and Olympus Lext 5000 profilometer. The corrosion resistance was examined in 3% NaCl solution using both potentiodynamic measurement and Electrochemical Impedance Spectroscopy. In order to examine the change in chemical composition of the surface layer, the X-ray photoelectron spectroscopy study was performed. Results show that the use of a long laser pulse contributes to the formation of a thin, tight, rich in chromium passive layer, which significantly improves corrosion resistance in comparison to the reference sample. Different behaviour is observed after irradiation with an ultra-short pulse duration laser.

“…When rolling or BB is applied to metastable austenitic stainless steels, such as the aforementioned AISI 304 and AISI 316L, the austenite (γ-phase) transforms into martensite (ε- and/or α’-) due to a recrystallization change caused by deformation energy, even at ambient temperature. On the other hand, a smooth surface topography with very little roughness (Ra criterion from 0.8 to 0.025 μm) can be achieved after rolling or BB is applied as a finishing process [ 18 , 19 ]. This way, two of the abovementioned negative effects of the cutting finishing methods on fatigue resistance can be avoided.…”

Impact of Ball Burnished Regular Reliefs on Fatigue Life of AISI 304 and 316L Austenitic Stainless Steels

et al. 2021

The present work describes an experimental investigation of the fatigue durability of AISI 304 and AISI 316L austenitic stainless steels, which have regular reliefs (RR) of the IV-th type, formed by ball burnishing (BB) on flat surfaces, using a computer numerical control (CNC) milling center. The methodology and the equipment used for obtaining regular reliefs, along with a vibration-induced fatigue test setup, are presented and described. The results from the BB process and the fatigue life experiments of the tested austenitic stainless steels are gathered, using the approach of factorial design experiments. It was found that the presence of RR of the IV-th type do not worsen the fatigue strength of the studied steels. The Pareto, t-test and Bayesian rule techniques are used to determine the main effects and the interactions of significance between ball burnishing regime parameters. A stochastic model is derived and is used to find when the probability of obtaining the maximum fatigue life of parts made of AISI 304 or 316L reaches its maximum value. It was found that when the deforming force, the amplitude of the sinewaves and their wavenumber are set at high values, and the feed rate is set at its low value, the probability to reach maximum fatigue life for the parts made of AISI 304 or 316L is equal to 97%.
