“…Ion implantation improves the physical and mechanical properties of the material surface (hardness, heat resistance, wear resistance, fatigue strength, corrosion resistance, etc.) [20,[26][27][28][29][30]. The main advantages of ion implantation include the absence of adhesion problems [31] (since ions are implanted into the material at an energy of about 106 eV) and no influence on the geometric dimensions of workpieces, which is relevant for cutting tools or threaded joints [32].…”

In this work, the corrosion resistance of AISI 321 stainless steel is increased through. the two-stage implantation of oxygen ions and of both aluminum and boron ions together. During ion implantation, a modified layer with a thickness of about 200 nm is formed, which affects the properties of material. The increase in corrosion resistance is confirmed by prolonged acid corrosion tests at pH 3.5 and by accelerated electrochemical tests using a potentiostat. The corrosion rate of the implanted sample is 0.708 μA/cm2, in contrast to the non-implanted sample (1.26 μA/cm2). The modified surface layer is examined using X-ray photoelectron spectroscopy (XPS), secondary-ion mass spectrometry (SIMS), and transmission electron microscopy (TEM). Aluminum and boron are implanted to a depth of more than 250 nm. It is found that the modified surface of the stainless steel substrate contains oxides of implanted ions (Al2O3) and oxides of substrate ions (Cr2O3 and NiCr2O4).

[6][7][8][9] Currently, the prevailing heat treatment procedure involving solution treatment followed by deep cryogenic treatment (DCT) and tempering is commonly employed to attain a microstructure consisting of refined lath martensite, nano-M 2 C(M = Mo, Cr, Fe) precipitates, and residual austenite films. [10,11] This treatment approach serves to enhance the strength and toughness characteristics of the materials.…”

The hierarchical martensite structure of secondary hardening low‐carbon high‐alloy bearing steel at different solution temperatures is characterized in detail, and the effect of microstructural evolution on mechanical properties of the experimental steel is studied. The results show there are a large number of micron‐M6C at the boundary of the prior austenite grain when the solution temperature is 1,000–1,025 °C, which is conducive to hinder the growth of the prior austenite grain and produces smaller packets that improve the yield strength of the material. At the same time, such micron‐M6C is prone to stress concentration when the material is subjected to an external force load, which can severely reduce the material toughness. The M6C completely dissolves into the matrix when the solution temperature exceeds 1,050 °C, and the packets size grows rapidly with the prior austenite grain size. At this point, the effect of packets on yield strength no longer dominates, and the rate of decrease in yield strength tends to be gradual. Under the comprehensive function of the micron‐M6C‐remelting, the martensitic blocks refinement, the increased number of the Σ3 grain boundaries, and the growth of cracks can be hindered, and the toughness of material can be improved accordingly.

“…CSS-42L aviation bearing steel with good wear resistance is one of the most promising bearing materials in the future. [1][2][3] MXene with excellent mechanical and thermal properties is a 2D nanomaterial, and its strong adhesion property has great application potential in the field of tribology. The self-lubricating film formed by MXene composites could significantly reduce the friction at the interface.…”

To improve the antifriction and vibration reduction performances of oil-film bearings in hydroelectric generating set, textured CSS-42L surfaces filled with Sn-Ag-Cu-Ti3C2 (TSs-SACT) were prepared, and the friction and vibration experiments under oil lubrication were carried out. The results showed that TSs-SACT with texture pitch of 600 μm and MXene of 5 wt.% (TSs-SACT(5%)-600) had the best antifriction, which reduced the fluctuation amplitudes of frictional forces and suppressed the friction-induced vibrations. The wear morphologies were improved by the synergistic effects of oil, grooves and Sn-Ag-Cu-Ti3C2, and TSs-SACT(5%)-600 with uniform profiles had the excellent wear resistance. The complexity of surface profiles could be characterized by fractal dimension, which can be enhanced by Sn-Ag-Cu-Ti3C2. TSs-SACT(5%)-600 with complex profiles keeps good antifriction during lubrication state transitions, which effectively improves the operation reliability of oil-film bearing in hydroelectric generating set.
