“…There are many surface engineering methods that can be used to modify the physical and chemical properties of artificial joints and extend their service life. They include fluorescent processing, laser processing, sol-gel methods, physical vapour deposition, chemical vapour deposition, thermal spraying, electrophoresis, electroplating or a combination of these [1,13,[19][20][21]. Each technique will have a different effect on the chemical composition, structure and properties of the surface and, therefore, a different application will be achieved.…”
