Corrosion, being a destructive process, causes damage in almost all industrial sectors. In this way, it is harmful both from an economic, social and, especially, safety point of view, as it can cause failures in critical equipment and components of an industrial process. At this point, stainless steels are considered the most corrosion resistant metals. The resistance depends on the chemical composition and microstructure, factors that directly influence the passivation of these materials. The resistance is proportionally related to the addition of chromium (Cr) to the mixture, as well as other alloying elements, among which is the molybdenum (Mo), whose main function is to maximize corrosion resistance in the marine atmosphere, as in case of austenitic stainless steel AISI 316 which presents in the chemical composition a percentage of the element Mo. Austenitic stainless steels are applied in instrumentation systems in tubing for reliability in severe atmospheres in accordance with ASTM A269 which establishes the materials applicable to this function. Thus, the present work presents, through a review and case study, Pitting Corrosion of tubings of austenitic stainless steel AISI 316 in the presence of chloride ions (Cl-) coming from the marine atmosphere. The results show that there is no change in the longitudinal and transverse structure for all analyzed tubes, showing a homogeneous austenitic structure, free of intergranular precipitations.

In recent years, 3D scanning and printing of plastics has rapidly matured while printing of metallic parts is only gaining popularity due to required refinements of technology combined with cost- and resources effectiveness for the main components of printers and consumables. The 3D printing allows producing complicated shapes that can be hardly produced by conventional mechanical tools and can provide the functionalization of surfaces. In this work, several different stainless steel (AISI 316 L) surface patterns (flat, gecko’s fibrils, dimples, pyramids, mushrooms, mesh, brush, inclined brush) intended for controlling the coefficient of friction were printed with the help of a 3D metal printer by selective laser melting technique. Unidirectional sliding tests were performed with pin-on-disc configuration. Sliding velocity of 5 × 10−3 m/s and continuously increasing load ranged from 5 to 103 N has been applied in the course of “scanning” mode and accompanied by simultaneous recording of the coefficient of friction. A stainless steel (AISI 316) disc counterbody was used in this series of the tests. It was found that the 3D printed structures allow to control the value and stability of the coefficient of friction in a wide range of loads. Microstructural analysis of the worn samples was performed to support the conclusions regarding wear mechanism.
