Surface engineering of hybrid joints for sub-assembly

Service life of a self-pierced riveted joint is affected by various types of corrosion and fretting. Application of a coating to the self-pierce rivets can increase the corrosion and mechanical properties of the rivet and the joint. Nanocrystalline materials provide advanced properties to microcrystalline material therefore, in this thesis nanocrystalline zinc-tin coatings were synthetized as an advanced coating for self-piercing rivets and their corrosion and mechanical properties were compared with ultra-fine grained structured coatings.
