Temperature of anode nitriding from 600 to 1050 °C is controlled by the 120–260 V.
Nitrided layer is 95 µm in the electrolyte of 10% NH4Cl and 5% NH3 for 10 min.
Weight wear of nitrided CP-Ti decreases from 57 mg to 0.52 mg at lubricant friction.
Corrosion rate of nitrided CP-Ti in H2SO4 (4.5%) and HCl (0.2%) decreases by 2 orders.
