“…4 ). Thus, the wear rate increased with increasing load, agreeing well with the existing studies on L-PBF-processed austenitic and PH SS 17 , 43 . The wear rate at 3 N is lower around one fifth of the value of an L-PBF-processed austenitic SS (k = 3.50 ± 0.3 × 10 −5 mm 3 /Nm, 229 HV) under the same tribological conditions, as reported in a previous study 8 .…”

The dry sliding wear behaviour of a high carbon martensitic stainless steel (HCMSS) consisting of ~ 22.5 vol% of chromium (Cr)- and vanadium (V)-rich carbides processed by electron beam melting (EBM) has been captured. The microstructure consisted of martensite and retained austenite phases with a homogeneous distribution of sub-micron-sized V-rich and micron-sized Cr-rich carbides, leading to relatively high hardness. The CoF decreased ~ 14.1% with increasing load in the steady-state, due to the material transferred from the wear track over the counterbody. The wear rate of the HCMSS compared to martensitic tool steel processed in the same manner, and it was nearly identical under low applied load. The dominant wear mechanism was removal of the steel matrix through abrasion, followed by the oxidation of the wear track, while three-body abrasive wear occurred with increasing load. A plastically deformed zone beneath the wear track was revealed through cross-sectional hardness mapping. Specific phenomena occurred with increasingly aggressive wear conditions were described with carbide cracking, pull-out of V-rich carbides and matrix cracking. This study revealed the wear performance of the additively manufactured HCMSS, which could pave the way for producing components for wear-related applications ranging from shafts to plastic injection moulds via EBM.

“…However, the additives never reduced the friction of the ISO 68 mineral oil to the friction range of the considered bio-oils, which suggests that they have inherently superior friction performance properties. The dominant mechanism for wear in all the cases appears to be due to abrasive wear with some adhesion, which is similar for lubricated conditions as observed in a previous study [7]. The wear surface is mainly due to two-body abrasion where surface asperities are directly in contact with the boundary lubrication regime.…”

“…Another major product of fossilbased oil is lubricants that prevent contact between asperities by forming a thin film or layer. Without adequate lubricants, the contact between two surfaces could lead to severe wear and eventually to catastrophic failure [7]. A lubricant acts as a protective layer for the longevity of the surfaces, transfers heat during operation, and reduces friction.…”

This study investigates the wear and chemical properties of several vegetable-based oils based on different oleic content and compares them to a standard mineral base oil and inherent chemistries. A ball-on-disk tribometer test was performed to analyse the tribological properties of the oil under 50 N of applied load and at varying speeds. The functional groups of oils were tested using Fourier Transform Infrared Spectroscopy (FTIR) and viscosity was determined using a rheometer. Bio-derived oils had a lower coefficient of friction (COF) than the standard mineral base oil at different speeds. The presence of oleic acid in the vegetable oils helped to reduce the friction between the surfaces as compared to that of the mineral base oil. The presence of oleic content played a vital role during the wear analysis where high oleic content oil had lower wear compared to other bio-based oils and the standard mineral base. Abrasion was observed to be the dominant wear mechanism from the optical profilometer that included grooves on all the surfaces of the disk samples. The results showed that high oleic content oil has good potential to be an alternative to the standard mineral base oil.

“…With a normal load increase to 5 N, the cracking mechanism becomes dominant, which results in the formation of severely worn grooves and many parallel cracks. In turn, Sanjeev et al [41] showed for additive manufactured 17-4PH steel tested under dry sliding wear conditions, adhesive smearing is the dominant wear mechanism. The review of the above-mentioned studies indicates that fatigue cracking initiates at a load of 10 N, which is the load value applied in this study.…”

Components produced by additive manufacturing (AM) via direct metal laser sintering (DMLS) have typical as-fabricated surface defects. As a result, surface properties of AM products should be modified to increase their strength, anti-wear behaviour, and at the same time to ensure their high corrosion resistance. Surface modification via shot peening is considered suitable for additive manufacturing of medical devices made of 17-4PH stainless steel. The objective of this study was to determine the effect of shot peening pressures (0.3 MPa and 0.6 MPa) and three types of blasting media (CrNi steel shot, nutshell granules and ceramic beads) on the tribological characteristics and corrosion resistance of specimens of DMLS 17-4PH stainless steel. Results demonstrated that shot peening caused steel microstructure refinement and—except for the nutshell shot-peened specimens—induced both martensite (α) formation and retained austenite (γ) reduction. 17-4PH specimens peened with steel and ceramic shots showed the highest increase in surface hardening by approx. ~ 119% (from 247 to 542 HV), which significantly improved their wear resistance. The highest mechanical properties (hardness and wear resistance) and corrosion resistance were obtained for the surfaces modified using the following media: ceramic beads > CrNi steel shot > nutshell granules. Adhesive and fatigue wear were two predominant mechanisms of tribological deterioration. Results demonstrated that the application of shot peening using ceramic beads led to grain size refinement from 22.0 to 14.6 nm and surface roughness reduction, which in turn resulted in higher corrosion resistance of the material. DMLS 17-4PH specimens modified by shot peening using ceramic beads and a pressure of 0.6 MPa exhibited the optimum surface morphology, hardness and microstructure, and thus improved wear and corrosion performance.
