“…The impedance of the TiN-40 and the TiN-80 samples at 40 Hz was 1.24 Ω and 1.18 Ω, respectively, and increase to 1.35 Ω and 1.39 Ω. Evidently, the impedance values rise in all cases influenced by the skin effect. The skin effect depth of the pure substrate was calculated using equation (1).…”

In the present work, the effect of the deposition time on the structure and electrical impedance of reactive DC magnetron sputtered TiN coatings was studied. The structure of the coatings and the substrates was studied using X-ray diffraction (XRD). The electrical impedance and high frequency stability of the specimens was experimentally measured and the results were indicative of whether the application of the coatings as protective layers between the electrical contact pads of electrical contact systems is feasible.

“…In this section, by numerical calculations, we show the phenomenon of the bio-lubricant dynamic viscosity variations across the very thin bio-liquid layer. Presented in the next intersection Figures 4,5,6,7,8 show the gap filled by the thin (ε= 12 micrometer height) physiological lubricant layer, restricted by the two cooperating phospholipid (PL) bilayer. Numerical calculations are performed using UNR-Mega Algorithm [36] for: Wettability We = 60°, pH = 6, the concentration of collagen fibers δ v = 4, bio-liquid flow index n = 0.9.…”

This paper presents new non solved, scientific research directions and their applications in contemporary non-conventional lubrication problems of the bio-surfaces domain. Here are described new research scientific trends and research problem solutions of hydrodynamic lubrication for living tissue, human skin and human cartilage joints surfaces. At first in introduction is described the state of the art, a new purpose of anticipate research and the bio-tribology connections with other scientific domains are documented. The bio-tribology is a new scientific domain where the bio-properties of living, mutually cooperating bio-materials have an important influence on joint human functioning and on the consequences of obtained bio-tribology effects. Using experimental and numerical methods, the main result is focused on the influence of the bio-sweat dynamic viscosity variations across the film thickness on the load carrying capacity of the lubricated human skin and limbs.

“…AISI 304 stainless steel is extensively used in different industries, such as aerospace, automotive manufacturing, medical, pharmaceutical and food, because of its considerable corrosion resistance as well as superior mechanical properties. Furthermore, low thermal conductivity, improved work-hardening ability and strong material adhesion to the tool’s cutting edges are the main reasons for this alloy’s considerably low machining capability and decreased machined surface quality (Muthusamy et al , 2016; Kumar et al , 2022). One engineering approach to minimize machining environmental damage is eliminating cutting fluids entirely and applying dry machining technique.…”

Purpose First, the effect of magnetic field intensity and nano-ferrofluid concentrations on surface roughness was evaluated in magnetic minimum quantity lubrication (MMQL). Then, the effect of lubricant flow rate and nozzle position on surface roughness was investigated in MQL, MMQL, electrostatic MQL (EMQL) and electromagnetic MQL (EMMQL). Design/methodology/approach This study examined the performance of MQL under magnetic and electric fields in turning AISI 304 stainless steel in terms of surface roughness and compared the results with those obtained from wet cutting and MQL turning operations. To prepare the nano-ferrofluid used in different states of MQL, Fe3O4 nanoparticles were added to the base fluid. Findings The results showed that the surface roughness under the EMMQL technique decreased by 36% and 49.4% on average compared with wet and MQL techniques, respectively. The lubrication technique affected the surface roughness by 90.2%, whereas it was 8.3% for the lubricant flow rate. EMQL and EMMQL techniques had no significant difference in their effects on surface roughness. In the innovative MMQL technique, the nano-ferrofluid concentration of 6% and magnetic field intensity of 93 G resulted in lower surface roughness of the workpiece relative to other counterparts. Originality/value Examining previously published studies showed that using nano-ferrofluids under a magnetic field for cooling purposes in machining processes have less considered by researchers. This study applies an innovative method of lubrication under the concurrent effect of magnetic and electric fields, called EMMQL, to improve the efficiency of MQL in machining hard-to-cut materials. For comprehensively inspecting the newly presented method, the effects of several parameters, including the nano-ferrofluid concentration, magnetic field intensity, lubricant flow rate and position of lubricant spray nozzle, on the surface roughness of workpiece in turning of AISI 304 stainless steel are investigated.
