“…Using the Taguchi method, the difference between experimental and desired values is calculated using a loss function. Further, the loss function is converted to the signal-to-noise ratio (S/N) [42,43]. Normally, S/N ratios are analyzed according to three kinds of quality characteristics: lower is better, higher is better, and nominal is better [41].…”

Proper rolling bearing lubricants and lubrication procedures are critical for delivering adequate bearing performance in critical situations. Main roles of Zirconium di oxide (ZrO2) nanoparticles in engine oil as lubricant additive for rolling bearing are reduction of wear and friction, extension of fatigue life, removal of frictional heat, and protection from corrosion. The present work investigates the tribological properties of SAE20W40MGO and ZrO2 nano particles in SAE20W40 MGO oil for 0.4% concentration between steel/steel contact. In order to study wear under variable speed conditions, four-ball wear tests were carried out with chrome-plated steel balls (Grade E-52100), which were designed using 2 levels of factorial design of experiments (DOE). Nano-lubricant deterioration with and without ZrO2 were determined using empirical equations to project wear with reference to speed and ZrO2 concentration. Results presented that anti-wear properties of the SAE oil samples enhanced with ZrO2 irrespective of speed range.

“…The composites mechanical properties are influenced by the weight percentage or volume, size of reinforcement in the matrix and also by the interactions between the matrix and reinforcement [27]. Addition of B 4 C and fly ash in aluminum improved the mechanical properties of AHMCs [28][29][30].…”

Aluminium hybrid matrix composites (AHMCs) is employed in the automotive and aerospace industries because to their high strength-to-weight ratio, corrosion resistance, and tribological properties. The objective of this research is to examine the metallurgical, mechanical, and corrosion characteristics of Aluminum hybrid matrix composites (AHMCs) produced by reinforcing LM25 alloy with 5% fly ash and varying percentages (4%, 8%, 12%) of TiB2 using the stir casting technique. The uniform distribution of reinforcing particles was verified by capturing images via SEM and EDAX. Density, Tensile strength, microhardness was conducted for the prepared AHMCs. The outcome reported there was an enhancement by adding reinforcement particles of fly ash and TiB2 comparing to the pure LM25 alloy. This improvement was attributed to the presence of fly ash and TiB2 particles, resulting in a higher dislocation density, with increasing TiB2 content demonstrating improved strength and ductility compared to conventional LM25 alloy.

Design of experiments is a statistical approach from which an optimized number of experiments is determined. Taguchi design of experiments, applied on Erichsen tests, is chosen to be considered in this paper. The most important parameters in this forming process, Erichsen index ( IE), and maximum generated force ( Fmax), are experimentally and theoretically determined. Three input factors are selected, at diverse levels, in order to study their influence on Erichsen output results. The considered input factors are sheet thickness, punch diameter, and friction coefficient. New mathematical models which take into account the effects of these factors and their interactions are developed. Moreover, the influence of Erichsen test on the S235 steel microstructural behavior is experimentally examined as function of the sheet thickness. A good agreement between experimental and theoretical findings proves that the proposed models provide a precise prediction and an exact estimation of the Erichsen output parameters ( IE and Fmax). The efficiency of the adopted design of experiments via Taguchi method is well confirmed.
