“…For this friction system in general, the actual contact area is proportional to about the normal load to the power of 2 / 3 , so the friction coefficient decreases accordingly as the load increases. These results agree with those for similar friction systems reported in the literature. − …”

High-hardness and wear-resistant ceramic coatings were obtained on 5052 aluminum alloy by the microarc oxidation (MAO) process in silicate electrolytes with different nanoadditives (TiO2, Si3N4), and the effects of different nanoadditives on the microstructural and mechanical properties of the ceramic coatings were systematically studied. The microstructure results revealed that the nanoadditives could improve the thickness and compactness of the ceramic coatings. The X-ray diffraction results demonstrated that the nanoadditives were successfully incorporated into the MAO coatings and that some new phases of Si2N2O and TiN were formed, enhancing the comprehensive performance of the ceramic coatings. Furthermore, the distributions of elements determined from energy-dispersive X-ray (EDX) spectroscopy and cross-sectional images displayed a good homogeneity to support the excellent mechanical properties of the ceramic coatings. Therefore, the average microhardness, the full indentation force–depth curves, the hardness and elastic modulus, and the H/E and H 3/E 2 ratios of the ceramic coatings with TiO2 and TiO2 + Si3N4 nanoadditives delivered a very high hardness, implying good antifriction properties. Moreover, the friction coefficients of the ceramic coatings also demonstrated their outstanding wear resistance. Finally, the corrosion resistance and electrochemical impedance spectroscopy results further revealed the compactness of the ceramic coatings, indicating a high hardness and abrasion resistance.

The direct metal/metal sliding contact causes a severe wear with a high friction coefficient and an important wear rate. Applying magnetic field into the rotating sliding steel Fe360 B/steel Fe360 B modifies the friction and the wear behavior of the contact. The experimental tests were conducted in three different environments such as: ambient air, pure oxygen at 105 Pa and high vacuum at 5.10−5 Pa. In ambient air and without magnetic field, the metal/metal contact is ductile. When a magnetic field is applied, the formation of oxide layer evolves progressively with the number of sliding cycles. This contact has a low friction and mild wear. Under oxygen, the oxide film appears in wear track with and without applied magnetic field. The wear rate under oxygen is lower than that in ambient air with a ratio roughly equals to 10. In oxygen, the average value of friction coefficient µ decreases from µ = 0.41 to µ = 0.30. In vacuum, the increase of surface hardness causes a transfer of particles from the disc towards the pin. This transfer modifies the morphology of the wear track, increases the surfaces roughness and leads to a strong adhesive wear. The different analysis obtained with: microscopy, micro-harness, wear losses, EDX and friction evolution explains the effect of applied magnetic field on the friction behavior of Fe360 B steel.

“…Further studies have shown that the wear resistance of high-speed steel [18] mild steel [19], medium steel [20] and bearing steel [16] improved as a result of magnetic field treatment. By applying a magnetic field during testing, Wei et al [21] and Tharajak and Nicomrat [22] observed a decrease in the friction coefficient. They attributed their observations to the applied magnetic field leading to oxidation on the surface and promoting finer wear debris particles.…”

In the present paper, the tribological properties of untreated and magnetically treated EN8 medium-carbon steel were studied. Tribological tests were performed using a pin-on-disc friction and wear tester. The alternating magnetic field treatment has led to a reduction in the coefficient of friction by 18% and of the wear rate by 41% and to decreases in the surface roughness and the wear scar width by 30% and 12% respectively. Examination by means of transmission electron microscopy attributed these results to increased dislocation mobility and migration to the surface as a result of alternating magnetic field treatment leading to an increase in the Vickers microhardness and to an increase in compressive residual stresses at the surface.
