Nickel-based composite coatings, incorporating nanoparticles such as Y2O3, have gained significant attention due to their superior mechanical, tribological, and anticorrosion properties. These coatings are extensively used across industries including transportation, energy, and manufacturing. The study of composite coatings dates back to 1928 when...

This study investigates the efficacy of ZnCl2 as a corrosion inhibitor for mild steel across varied pH environments (3.5, 7, and 10). Findings highlight a significant reduction in corrosion rates with increasing ZnCl2 concentrations, pinpointing optimal levels at 350 ppm (pH 3.5), 575 ppm (pH 7), and 325 ppm (pH 10). Through comprehensive experimen...

This research explores “Ni–Al2O3” composite coatings produced through conventional electrodeposition, examining their corrosion resistance about variations in alumina concentration, bath temperature, and applied electrical current. Unlike previous studies, this research introduces a new fuzzy inference model, used in conjunction with polarization t...

Public transport via trams has become increasingly important in daily life to meet the growing demand for economic and environmental considerations. In order to ensure the safety of the railway system and reduce service costs, it is necessary to understand the tribological behavior of the system. There are various types of damage such as fatigue, w...

The nature and complexity of the manufacturing process for composite coatings make it difficult to predict or even measure the technical and economic performance of manufacturing, which is why great attention has been paid to the manufacturing methodologies of these coatings and their properties, in particular the mechanical properties. In this wor...

The wheels and rails of the train, tram etc. are often verified from their microstructure and plastic deformation, which usually appear in the outer layer of a wheel and rail, to analyse the causes of geometrical defects by monitoring the applied loads and variation of the temperature as suggested in the literature. This paper studies the effect of...

One of the most important phenomena associated with machining operations is the cutting temperature because it affects the life of the cutting tool. Cutting parameters and insert material are the important conditions that affect temperature in turning. In this study, tests were carried out on X 200 Cr 12 steel during turning process. In ordre to me...

Minimizing machining time is an objective that must be taken into account when choosing the cutting tool. The diameter of the cutting tool is one of the parameters which greatly influences the machining time of different geometric shapes, especially pockets. In this study, a methodology for optimizing the choice of milling cutting tools for machini...

During the cutting, knowledge of thermal phenomena induced is essential for the understanding of the cut and to improve the machinability of certain materials. Moreover, these temperature influence the final product (residual stresses, surface states, geometrical tolerances, etc.) Experimental techniques were used to measure the cutting temperature...

The surface response method is widely used in many sectors of the industry, this method is a set of statistical and mathematical techniques used to minimize or maximize the factors of production by optimizing inputs factors.

The monitoring of the machining process has become a preliminary step in the mechanical manufacturing processes, especially for the electrical discharge machining (EDM). However, the monitoring of the electrical discharge machining process remains an ill-defined problem and is generally based on heuristics that are difficult to model. Therefore, ar...

Metal cutting represents a large portion in the manufacturing industries, which makes this process the largest consumer of energy. Energy consumption is an indirect source of carbon footprint, we know that CO2 emissions come from the production of energy. Therefore high energy consumption requires a large production, which leads to high cost and a...

The choice of electrodeposition parameters for nickel-alumina composites Ni-Al2O3 is very difficult because of the complexity and high cost of the experimental tests, as well as the absence of an exact mathematical model. For this reason, it is essential to use more efficient techniques taking into account all the advantages of formulating the prob...
