Wear behavior of iron boride coating on AISI 4140
Protection of Metals and Physical Chemistry of Surfaces, 2016 A new paste technique was established for making boronising coatings. This method gave iron boride coatings a unique wear and tear property something that was tested as a microstructural feature. The coats were acquired from obtained by transmission of boron molecules from ferrobor concentrates to steel surface.

International Journal of Ceramic Engineering &Science, Volume 6, Issue 6, November 2024.Abstract In this study, the role of MgB2 in composite coatings is pivotal. Electroless Ni–B plating, a current‐free chemical reduction process, deposits nickel–boron coatings. Other than MgB2, reinforcements like SiC, B4C, and so forth are used with Ni–B coatings for improved properties.

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 11, Page 4000-4011, November 2024.Abstract In this study, multifunction cavitation (MFC) was performed on low‐alloy steel (AISI 4140 steel) rods with different hardnesses to increase their fatigue limit. It was found that a high compressive residual stress was generated on the surface of steel rods by MFC and that the magnitude of the compressive residual stress tended to increase with
