|Abstract: ||Bulk metallic glass or amorphous alloys are multi-component and approximate deep-eutectic alloys that offer extra-ordinarily high hardness, elastic limit and corrosion resistance but find limited application in bulk structural applications due to their extremely poor tensile ductility and toughness and restricted size/thickness to which they can be directly cast or fabricated. These alloys or bulk metallic glass can be good candidates for wear/corrosion resistant coating on tough metallic components.
Laser surface cladding has traditionally been used to produce hard and corrosion resistant surfaces on the steel substrates. Due to rapid cooling rates associated with laser surface engineering, it is logical to anticipate that laser cladding of an alloy with high glass forming ability is likely to produce an amorphous surface or ultra fine grained coating with high hardness and wear resistance. The present study is aimed at developing a wear resistant coating on SAE 52100 steel by laser ...|
