Özet

Coating processes are of great importance for protecting the materials used in the industry from the damaging effects of external environments and mechanical forces. There are a wide variety of coating methods, but the electrochemical deposition method within them is one step ahead because of its low cost, easy manufacturability and rapidity. Ni-B coatings have been produced for many years by the electroless deposition method, but electrodeposited Ni-B coatings are a relatively new research topic and attract much attention in recent years. Due to its superior properties Ni-B alloy coatings are successfully used in many industries such as aerospace, automotive, petrochemical, chemical and electronics. Works on reinforcing Ni-B alloys with second phase particles to increase these properties to a better level has been increasing rapidly in recent years. Ni-B alloy and composite coatings were investigated in this study. Furthermore, the bath components, production parameters, contents and properties of Ni-B alloy matrix composite coatings were presented comparatively. It was revealed that reinforcing the Ni-B alloy matrix with ceramic particles affected properties such as crystal structure, morphology, hardness, corrosion and abrasion resistance very seriously.
