Investigation of the Structural, Mechanical, Tribological and Electrochemical Properties of B4C Films Deposited by Different Techniques

Year: 2025

Abstract: Because of its superior mechanical properties, excellent thermal stability, high wear and heat resistance and remarkable resistance to chemical agents, B 4 C films are extensively utilized in a variety of industries, including armor materials and wear-resistant components. B 4 C films can be coated in a variety of ways. This study was aimed to obtain optimum structural, mechanical and tribological properties of B 4 C films grown by electrophoretic deposition (EPD) and RF magnetron sputtering techniques. The structural properties of the B 4 C films were investigated by SEM and XPS analysis. The tribological properties and the electrochemical properties were carried out using a wear tester and a corrosion tester, respectively. Examining the observed polarization resistance reveals that AISI 4140 steel has the lowest resistance (15.33 × 10 6 Ω cm 2 ) and the B 4 C film with EPD has the highest resistance (347.5 × 10 6 Ω cm 2 ). It was also observed that B 4 C films significantly reduced the coefficient of friction of the AISI 4140 steels. The AISI 4140 substrate and B 4 C films coated by RF magnetron sputtering and EPD have wear rates of 1.45*10 −4 mm 2 /Nm, 1.22*10 −4 mm 2 /Nm, and 9*10 −4 mm 2 /Nm, respectively.
