Tribological Behavior of the 316L Stainless Steel with Heterogeneous Lamella Structure

Abstract

In this paper, the tribological behavior of 316L stainless steel with heterogeneous lamella structure (HLS), prepared through 85% cold rolling technology and subsequent annealing treatment (750 °C, 10 min), were conducted on a ball-on-disc tribometer under different normal loads in dry ambient air conditions. The morphologies, structures, and compositions of the raw and worn surfaces were analyzed by 3D surface profilometer, XRD, SEM, EDS and TEM. Based on this, the results showed that the HLS 316L stainless steel samples exhibited lower and more steady friction coefficients than coarse-grained samples, especially under higher loads, which can be attributed to the existence of numerous oxidative particles across sliding interfaces. However, the wear resistance of HLS 316L stainless steel sample was a little weakened compared to that of the coarse-grained sample under a normal load of 5 N. When the load increases up to 15 N, an obviously decreased wear resistance was found for the HLS of the 316L stainless steel sample, which was 50% lower than that of coarse-grained sample. This can be ascribed to the more severe oxidative and abrasive wear performance of HLS 316L stainless steel sample under dry sliding conditions.

“…If the surfaces move in relation to each other, fragments of the material may be “torn” from them—this is called adhesive wear. A similar phenomenon was noticed in many other studies in which steel was combined with steel [ 49 , 50 , 51 , 52 ]. In order to check whether there was adhesion in the tested samples, as was also the case previously, SEM was used.…”

The Influence of the Powder Characteristics on 316L Stainless Steel Coatings Sprayed by Cold Gas Spray

“…Similar CoF were measured for all the coatings prepared by CGS, independently of the powder used for their deposition. The 316L bulk CoF, 0.746, is close to results seen in literature with the same testing load, 0.7 [57] and 0.8 [58]; however, the CoF of all the coatings were higher than the bulk, with the highest CoF for the 316L-APS, 0.934.…”

“…From the comparison of these results, it can be interpreted that the coating obtained with the water atomized (316L-CGS_1 and 316L-CGS_2) and gas atomize (316L-HVOF) powders allow obtaining 316L coatings with an abrasion resistance eve higher than a 316L bulk material. The abrasion resistance of a material is directly related to its Young´s modulus (E hardness, toughness, and compactness as presented by Fu, Li, and Li [58]. According t this, the close values for the abrasion results on the rubber wheel testing, for these thre The abrasion resistance of a material is directly related to its Young s modulus (E), hardness, toughness, and compactness as presented by Fu, Li, and Li [59].…”

Improving the Wear and Corrosion Resistance of Maraging Part Obtained by Cold Gas Spray Additive Manufacturing

“…The mean CoF values after the wear regimen stabilized are indicated in Table 4. The value indicated for the reference material 316L bulk, 0.67, is close to the value presented in the literature, 0.7 [16,49]. The CGS MAM maraging presented the highest CoF, 0.86, while the WC-10Co4Cr had the lowest, 0.14, among the evaluated materials.…”
