Steel 316L was coated with titanium or titanium nitride by ion plating. The tightness of the coatings was examined electro-chemically. The galvanic effects for the galvanic couples steel-titanium, steel-titanium-coated steel and steel-titanium nitride-coated steel were studied. It was found that both titanium and titanium nitride coatings were non-porous in Ringer's solution; titanium served as an anode in the couple steel-titanium; it was oxidized according to the logarithmic law. For the other two couples, the coatings were the cathodes. The rate of dissolution of steel in these couples, was however, smaller than expected, owing to a strong polarization of the coatings. The potential of the couple was similar to that of steel.
316L不锈钢通过离子镀覆钛或氮化钛。采用电化学方法检测涂层的致密性。研究了钢-钛、钢-镀钛钢和钢-氮化钛镀钢这几种电偶对的电化效应。结果发现，在林格氏溶液中，钛和氮化钛涂层均无孔隙；在钢-钛电偶对中，钛作为阳极；它按照对数定律被氧化。对于另外两个电偶对，涂层是阴极。然而，由于涂层的强烈极化作用，这些电偶对中钢的溶解速率比预期的要小。电偶对的电位与钢的电位相似。
