Wear Characteristics of Hardfacing Alloys: State-of-the-art

Life factor of machine parts depends on the wear and machine parts intended fracture due to effect caused by wear. Wear has typical modes such as abrasion, erosion, adhesive, impact and corrosion. Hardfacing is a resistance to wear, it is an application of build-up of deposits of special alloys on the surfaces. The wear resistance depends on the factors like hardfacing alloys, matrix materials, matrix hardening agents, temperature, erodent and abrasion particles. The present work report's a review on wear behavior characteristics of hardfacing alloys on some ferrous based alloy and nickel based alloys.
