A comparative study on wear behaviour of Cr/Mo surface modified grey cast iron

This paper presents laser cladding of grey cast iron with addition of Cr and Mo powder for enhanced wear properties. The laser cladding process was conducted using a Nd:YAG laser system. Sliding wear test were carried out on a linear reciprocating wear testing machine to analyse the wear rate during...
