“…It has been observed that tensile strength increases with a decreasing porosity and gain refinement. Pores are preferable zones for corrosion, which exhibit higher corrosion rates, and corrosion has been observed in the vicinity of pores [52]. An inversely proportional relationship exists between porosity and corrosion.…”

SS316L is an austenite-grade steel material offering a better strength-to-ductility ratio, higher corrosion resistance, and biocompatibility. In DMLS products, residual stresses are inevitable because of the thermal gradient involved in the process and the porosity that results from process limitations. As a result of these defects, the strength of the product is reduced and the quality of the product is compromised. The primary objective of this article is to offer an in-depth analysis of different heat treatment methods that are employed to achieve superior properties in products manufactured through DMLS processing. Thermal processing techniques include Hot Isostatic Pressing, Solution Heat Treatment, T6 heat treatment, Direct Aging Treatment, etc. Using thermal post-processing techniques, 99.99% of the porosity is eliminated, corrosion resistance is significantly increased, and mechanical properties are enhanced. This study examines the need for thermal post-processing, the methodology employed, and the property enhancements achieved by DMLS products. There are many factors affecting thermal post-processing, however, efforts have been made to review the details regarding thermal post-processing applied to SS316L material processed with direct metal laser sintering. Moreover, the specific methods for post-processing can be determined based on the product's intended application.

“…560 MPa), good wear resistance, widespread availability, favorable machinability, fracture toughness (max. 12.3 kJ/m 2 ), biocompatibility, weldability, and a relatively economical cost [17][18][19][20][21][22][23]. This alloy has opened new avenues, especially with the advent of L-PBF technology, leading to its exploration in hydrogen-related applications, aerospace endeavors, and nuclear industries.…”

This research aims to enhance the understanding of the interrelationships among the manufacturing process, microstructure, and mechanical properties in the Laser Powder Bed Fusion (L-PBF) of SAE 316L stainless steel (SS), which can lead to the appearance of undesirable phases, like sigma (σ). As part of this investigation, as-built samples underwent solubilization heat treatment (HT), primarily targeting the dissolution of the σ phase and microstructure homogenization, with a subsequent assessment of its impact on hardness. The study reveals the efficacy of HT in reducing σ phase content, particularly following treatments at 950°C and 1,050°C for 2 h. Notably, the dissolution of the process-induced microstructure becomes progressively significant within the temperature range of 800-950°C for 2 h. Furthermore, the study identifies a hardening effect associated with the process-induced microstructure on the samples. Remarkably, the sample exhibiting the highest hardness value featured a substantial σ phase content and maintained the process-induced structure after HT.

“…Due to the presence of the metal element molybdenum (Mo) in 316L stainless steel, it can withstand harsh working conditions [1], showing excellent corrosion resistance and weather resistance [2][3][4][5]. Therefore, this material is widely used in various engineering fields, such as harbor facilities [6,7], biomedical devices [8,9], and marine vessels [10,11]. However, when it is applied in a humid environment such as the ocean, the performance and service life of the material decreases [12][13][14][15].…”

In order to improve the anti-fouling of stainless steel surfaces in outdoor or humid environments, a superhydrophobic modification is often used to improve its self-cleaning performance. However, the mechanical stability of superhydrophobic surfaces remains a challenge. In this paper, a two-step preparation method was adopted to prepare the micro–nanocomposite coating, which innovatively combined “top-down” and “bottom-up” approaches, and also coupled together two key factors that affect superhydrophobicity: a rough microstructure, and low surface energy. The silver mirror, adhesion, and pollution-resistance results show that the composite coating samples, which were obtained by optimizing the preparation process, have excellent water repellency and self-cleaning properties. Meanwhile, the samples demonstrate outstanding mechanical stability, and can resist damage from sandpaper and tape. The two-step preparation method was simple, fast, and efficient. This method could be popularized and applied to the preparation of superhydrophobic surfaces on metal substrates.
