The mechanical performance and surface friction of graphene oxide (GO) were found to inversely depend on the number layers. Here, we demonstrate non-monotonic layer-dependence nanowear resistance GO nanosheets deposited a native silicon substrate. As thickness increases from ∼0.9 nm ∼14.5 nm, initially demonstrated decreasing then an increasing tendency with critical layers 4 (∼3.6 in thickness). This experimental corresponds change underlying wear mode overall removal progressive...
Multilayer Ti 3 C 2 T X nanosheets (MXenes) have gained notable attention in the tribological community due to their outstanding wear resistance induced by ability form beneficial tribolayers. Regarding delaminated, few‐layer x nanosheets, much less knowledge about performance is available. Therefore, this study aims at comparing solid lubrication of spray‐coated few‐ or multilayer coatings (dispersion concentrations and 5 mg mL −1 ). Linear‐reciprocating ball‐on‐disk tests are conducted...
Multi-layer Ti3C2Tx coatings have demonstrated an outstanding wear performance with excellent durability due to beneficial tribo-layers formed. However, the involved formation processes dependent on tribological conditions and coating thickness are yet be fully explored. Therefore, we spray-coated multi-layer particles onto stainless steel substrates create two different thicknesses tested their solid lubrication normal loads (100 200 mN) sliding frequencies (1 2.4 Hz) using...
Multicomponent alloys have attained general interest in recent years due to their remarkable performance. Non-equiatomic with boron addition as an interstitial element are being studied, exhibiting outstanding mechanical properties. In order estimate the behavior of potential alloys, thermodynamic and ab initio calculations were utilized this work investigate phase stability stacking fault energy (SFE) for (Fe50Mn30Co10Cr10)-xBx (x = 0, 5, 7, 10, 15 at.%) systems. Thermodynamic experiments...
The effect of boron doping in Fe50-XMn30Co10>Cr10Bx multi-component alloys on the resulting stacking fault energy has been experimentally and computationally assessed. Firstly, fcc hcp phases were identified together with faults along their (110) planes using high-resolution transmission electron microscopy. At same time, they theoretically predicted through thermodynamic CALPHAD ab-initio calculations. For boron-free alloy, was 23.5 mJ/m2 suggesting that deformation mechanisms relate to...
In recent years, research effort has been dedicated towards the exploration of MXenes’ solid lubrication performance verifying an outstanding wear due to formation beneficial tribo-films. However, resulting coefficient friction these coatings is rather high thus asking for further optimization. To tackle this short-coming, we designed sandwich Ti3C2Tx/MoS2 composite with overall goal combine low-friction (MoS2) resistance (Ti3C2Tx). The tribological composites having different stacking...
