Tribocorrosion of Passive Materials: A Review on Test Procedures and Standards

Figure 5

Effect of potential on the coefficient of friction and current during sliding (left) and on the wear track volume for a 316L steel in H₂SO₄ at cathodic (-1.5V) and passive (0V) potentials. The current values recorded are higher and the coefficient of friction is lower for passive potentials. The material loss at passive potentials is considerably higher due to wear-accelerated corrosion [55].
