Influence of nitrogen flow rate in reducing tin microdroplets on biomedical TI-13ZR-13NB alloy

Cathodic arc physical vapor deposition (CAPVD) is one of the promising techniques that have a potential to coat titanium nitride (TiN) on biomedical implants due to its good adhesion and high evaporation rate. However, this method emits microdroplets which have the possible detrimental effect on the...
