Dental decay still presents a major health problem among children. Its treatment usually requires the use of stainless steel crowns. This study compares the wear behavior of 316 L stainless steel and polyetheretherketone (PEEK) composite under identical test conditions. The wear tests were conducted in a reciprocating ball-on-plate tribometer (Plint TE67/R) using alumina balls as a counterface and artificial saliva as a lubricant at 37 °C to faithfully mimic oral conditions. The coefficient of friction (COF) and specific wear rate (k) values were determined and SEM/EDS examinations were performed to identify the predominant wear mechanisms. Results showed that PEEK exhibited a significantly lower coefficient of friction (COF = 0.094 ± 0.004) and thus lower wear volume (ΔV = 0.0078 ± 0.0125 mm3) and higher wear resistance, with an average value of specific wear rate of k = 9.07 × 10−6 mm3N−1m−1 when compared to stainless steel (COF = 0.32 ± 0.03, ΔV = 0.0125 ± 0.0029 mm3, k = 1.45 × 10−5 mm3N−1m−1). PEEK was revealed to be a potential material for use in pediatric crowns due to its high wear resistance while overcoming the disadvantages associated with steel at both an aesthetic and biological level.

“…Surface treatment is the most suitable and widely used technique for enhancing the cell-adhesion properties of 316L stainless steel [26][27][28][29]. Promoting cell adhesion and proliferation on the surface of a material is essential both for successful integration with host tissues and for optimal clinical outcomes.…”

In this study, the effects of three distinct surface treatment techniques on 316L stainless steel were investigated: low-temperature immersion corrosion, shot peening followed by immersion corrosion, and electrochemical corrosion. These techniques were selected with a focus on their potential implications for biomedical implant applications, as research gaps persist in understanding the influence of these treatments. A comprehensive examination of surface alterations was conducted using scanning electron microscopy, Raman spectroscopy, and α-step thin-film thickness profiling. Furthermore, human MG-63 osteoblastic cell line adhesion was evaluated using Liu’s stain and metallographic optical microscopy. Notable differences in cell-adhesion behavior based on the chosen surface treatment methods were observed. Specifically, weak cell adhesion was observed after low-temperature immersion and shot peening followed by immersion corrosion. In contrast, electrochemical corrosion, especially when conducted with a high current density and low corrosive-solution concentration, resulted in a uniformly corroded surface, which, in turn, promoted dense cell adhesion. Porous oxide layers were generated using all three techniques, but the efficacy of shot peening (applied at 1 kg/cm2 for 20 s) and electrochemical corrosion (using 0.5 M HCl) as promising processes were highlighted by our experimental results. Uniformly dense corrosion pits were produced through electrochemical corrosion, while semicircular grooves with small corrosion pits were the result of shot peening, both of which were found to be favorable for cell adhesion. The superior cell adhesion observed with electrochemical corrosion further emphasizes its suitability for biomedical applications.
