“…As the sliding distance increased, the contact period between the rotating disk and the sample face also increased, leading to further weight loss. The variation in weight loss can be attributed to material properties such as hardness, density, and softening behavior, as shown in Table 2, while increases tensile strength, weight loss decreases [28,29]. Using Equations 1 and 2 , calculated wear rates of investigated alloys mentioned above are plotted against the sliding distance.…”

Nanostructured Al-Sn and Al-Pb alloys are effectively used to improve their wear characteristics. Taking this into consideration, the wear properties of aluminum have been studied while affected by both elements Sn-Pb solder at a lower level to explore its reusing potentials. In this purpose a common pin-on-disk device is used in which different dry, wet and corrosive sliding environments are applied. Additionally, pure Al, Al-Sn and Al-Pb alloys are also considered for recovering the clarification and to separate elemental effects on wear properties. The worn surfaces of the samples are examined using optical and scanning electron microscopy, both before and after wear. Surface roughness also is a measure to assess the wear properties under different environments. The findings revealed that minor solder has a great impact on the wear properties of Al with Sn playing a better role than Pb. Solid solution strengthening is the main reason for improved wear behavior in terms of the low wear rate and coefficient of friction. Both Sn and Pb do not form any intermetallic with Al but with impurities it can easily occur particularly with Sn resulting in better wear properties. This phenomenon is more prominent in corrosive environment than wet due to the protective oxide layer on the surfaces. In dry sliding conditions, numerous large wear particles, oxide debris and grooves can be seen on the worn surface, but smoother wear tracks are seen in wet and corrosive environments as form oxide film and thumbs down somewhat direct contact on the moveable surfaces. SEM analysis also reveals higher abrasive wear and plastic deformation on the worn surface produced under dry sliding conditions where minor added alloys indicating that reinforcing particles effectively influence the properties.

“…This material is also recommended as a biomaterial due to its low carbon content, which increases its corrosion resistance to chlorinated environments [3,4]. The passive protective layer on the surface of SS material provides high prevention against uniform corrosion in ordinary oxidizing environments but can induce localized forms of corrosion under special conditions [5][6][7]. The existence of corrosive substances can lead to local passivation degradation and dangerous pitting [8][9][10].…”

Stainless steel is one of the materials with excellent corrosion resistance, so it is widely applied in various fields such as the chemical industry, aerospace, power generation, and biomedicine. The environmental condition (neutral, acidic, salty, or basic) is the most important thing to be considered prior to choosing palpable stainless steel materials. In this study, the corrosion behaviors of stainless-steel type SS 316L under exposure immersions in salty and acidic environments using sodium chloride (NaCl) and sulfuric acid (H2SO4) solutions were investigated, by referring to a standard method of ASTM G31-72. Scanning electron microscopy (SEM) results revealed that the specimen in NaCl solution exhibited a darker color, and relatively similar shape of cracks are observed. In contrast, the specimen immersed in H2SO4 was observed to have a large diagonal crack. The corrosion rate of SS 316L immersed in NaCl was lower with a value of 0.4260 mpy, compared to that of H2SO4 which was 2.5141 mpy. The Vickers hardness test showed that the hardness value of NaCl immersion was higher than that of H2SO4, which was 6.34% and 1.94%, respectively. It can be concluded that the SS 316L is better used in a salty environment compared to acidic conditions, because the main function of SS 316L is to be able to withstand rust, one of which is caused by chloride compared to other types of stainless-steel.
