Wear behavior of the surface alloyed AISI 1020 steel with Fe-Nb-B by TIG welding technique

Abstract

Abstract.Weld overlay coatings also known as hardfacing is a method which involves melting of the alloys and solidification for applied coatings. Recently hardfacing by welding has become a commonly used technique for improvement of material performance in extreme (high temperature, impact/abrasion, erosion, etc.) conditions.In the present study, the coatings were produced from a mixture of ferrous niobium, ferrous boron and iron powders in the ranges of -45 μm particle size with different ratio.

Manganese mono-boride, an inexpensive room temperature ferromagnetic hard material

“…Due to the exact nature of the bond in ferromagnetic crystals, a major challenge hindering the application of magnetic materials is the relatively soft mechanical properties and chemical instability91011121314. Considering that the boron chains have been successfully incorporated into the lattice of manganese metals, the mechanical properties of manganese mono-boride may be higher than that of traditional ferromagnetic materials.…”

“…However, most of ferromagnetic materials (FM) are metal alloys, magnetic ion oxides, rare-earth transition metal (R-T) intermetallic compounds which are dominated by the metallic bonds or ionic bonds, a bond feature that is unfavorable to resist shear strain and compress. The relatively low hardness, typically below the value of 5 GPa, of traditional magnetic materials inevitably impede the application of traditional magnetic materials in harsh conditions91011121314. To strengthen the mechanical properties of ferromagnetic materials, fabricating composite, ageing process, doping and controlling microstructure have been attempted to enhance mechanical properties789151617.…”

Enhancement of tribological and mechanical properties of TiB2 - Co cladded layer developed by tungsten inert gas cladding on AISI 1020 Steel

“…Up to now, many research groups have been utilized the tungsten inert gas cladding method to develop hard clad layer. Kilinc et al [24] improves the wear behavior of AISI 1020 steel by depositing Fe-Nb-B coating materials using TIG cladding technique. It was noticed that the Fe 12 Nb 5 B 3 and Fe 2 NbB phases present in the coating layer, resulting in wear rate decreases and microhardness increases.…”
