“…They measured the value of hardness for the XY, YZ, and XZ planes and found 262 HV, 239 HV, and 237 HV, respectively. Revilla et al [30] also showed a similar nature for the build orientation anisotropy of hardness. The hardness in the perpendicular direction is 289 HV, which is higher than the average value of hardness in the parallel direction, i.e., 272 HV.…”

“…Dewidar et al [38] also experimented with the porous structure for bone implants with 40% to 50% porosity, which has the desire elastic modulus of 26 GPa for the human body. Although the higher level porosity contributes to crack growth and failure mechanisms, the micro-pores' uneven distribution also plays a crucial role in the corrosion behavior [30]. Porosity also affects the creep life of the component.…”

“…Many researchers compared the corrosion behavior of SS316L with AM and wrought alloy in simulated body fluids. Revilla et al [30] reported interesting work by comparing the corrosion behavior of SS316L builds by different AM processes. Their work concluded that the highest corrosion resistance was found in the SLM part followed by LMD and wrought alloy as shown in the polarization curves of Figure 15.…”

Additive manufacturing (AM) is one of the recently studied research areas, due to its ability to eliminate different subtractive manufacturing limitations, such as difficultly in fabricating complex parts, material wastage, and numbers of sequential operations. Laser-powder bed fusion (L-PBF) AM for SS316L is known for complex part production due to layer-by-layer deposition and is extensively used in the aerospace, automobile, and medical sectors. The process parameter selection is crucial for deciding the overall quality of the SS316L build component with L-PBF AM. This review critically elaborates the effect of various input parameters, i.e., laser power, scanning speed, hatch spacing, and layer thickness, on various mechanical properties of AM SS316L, such as tensile strength, hardness, and the effect of porosity, along with the microstructure evolution. The effect of other AM parameters, such as the build orientation, pre-heating temperature, and particle size, on the build properties is also discussed. The scope of this review also concerns the challenges in practical applications of AM SS316L. Hence, the residual stress formation, their influence on the mechanical properties and corrosion behavior of the AM build part for bio implant application is also considered. This review involves a detailed comparison of properties achievable with different AM techniques and various post-processing techniques, such as heat treatment and grain refinement effects on properties. This review would help in selecting suitable process parameters for various human body implants and many different applications. This study would also help to better understand the effect of each process parameter of PBF-AM on the SS316L build part quality.

“…Some authors [ 81 , 82 , 83 , 84 , 85 , 86 ] suggested applying heat treatments to reduce this class of defects and increase microstructure uniformity. This way, corrosion resistance increased because when the microstructure is uniform, corrosion pitting or a non-uniform passive layer is reduced.…”

A Comparative Study of Corrosion AA6061 and AlSi10Mg Alloys Produced by Extruded and Additive Manufacturing

The aim of this work was to evaluate the corrosion behavior of the AA6061 and AlSi10Mg alloys produced by extruded and additive manufacturing (selective laser melting, SLM). Alloys were immersed in two electrolytes in H2O and 3.5 wt. % NaCl solutions at room temperature and their corrosion behavior was studied by electrochemical noise technique (EN). Three different methods filtered EN signals, and the statistical analysis was employed to obtain Rn, the localization index (LI), Kurtosis, skew, and the potential spectral density analysis (PSD). The Energy Dispersion Plots (EDP) of wavelets method was employed to determine the type of corrosion and the Hilbert–Huang Transform (HHT), analyzing the Hilbert Spectra. The result indicated that the amplitude of the transients in the time series in potential and current is greater in the AlSi10Mg alloy manufactured by additive manufacturing. The amplitude of the transients decreases in both alloys (AA6061 and AlSi10Mg) as time increases.

“…The tendency of steel 316L to precipitate second phases in the temperature range of 500 ... 800 ℃ is well-known. During operation in this temperature range, degradation of corrosion properties occurs for a long time [21,22]. In one of the previous works [23], it was found that the fraction of precipitates of the second phase (χ-phase) correlates with the energy density of the laser beam during selective laser melting.…”

Austenitic steel 316L is a common corrosion-resistant structural material used in a variety of industries from food to nuclear. There is a well-known tendency of steel 316L to precipitate second phases in the temperature range of 500 ... 800 ° С. During operation in this temperature range, degradation of corrosion properties occurs for a long time. Materials and parts obtained by modern methods of additive technologies are of great interest, since this method of alloys processing affects the thermodynamic equilibrium of the system and the kinetics of the release of second phases in aging alloys. The ability to control the kinetics of second phase formation is one of the key factors for improving the corrosion resistance of alloys. In this work, the effect of the method of steel 316L manufacturing (traditional and selective laser melting) on corrosion resistance at a temperature of 750 ° C for 100 hours in a KCl-NaCl environment was estimated. Corrosion tests were carried out, as a result of which it was found that a sample of 316L steel obtained by the method of selective laser melting has the lowest corrosion rate..
