Influence of Chemical Composition on Adhesion in Metallic Contacts
In sheet metal forming operations, adhesive wear is the main causeof tool damage as sheet material is transferred
to the tool surface during the forming operation. Means of reducing adhesive wear are of high interest for the metal forming
industry.In the present work, molecular dynamics simulations were used to investigate influence of alloying iron with
vanadium on adhesive properties in contact with iron. The results showed that adhesion, quantified by the work of adhesion,
decreased as the vanadium content increased. Highest reduction was obtained for 10 at.% vanadium which corresponded to a
decrease in adhesive work of approximately 10%.
