Scratch tests and reciprocating sliding tests were carried out under lubricated conditions to explore the influence of hard chrome plating on iron fines formation. In the scratch tests, the effect of hard chrome plating on iron fines formation at single asperity contact due to its inherent property have been investigated. In the reciprocating sliding tests, the initial roughness of the substrate and the roughness changes introduced due to the hard chrome coating have been taken into account. It was found that both the tribochemistry of the chromium layer and the smoothening of aggressive roughness features from the grinding process due to chrome plating play an important role in reducing iron fines formation. • Effect of hard chrome plating on iron fines formation due to its inherent property and surface roughness studied. • Tribochemistry of the contact interface with and without hard chrome plating studied. • Effect of hard chrome plating on surface roughness investigated. • Hard chrome plating reduced friction, material transfer and iron fines generated. • Surface chemistry of the chromium layer and smoothening of sharp roughness features influence iron fines formation.
