Abstract
A semi-conducting, stable polychelate coating is manufactured in situ on a conducting substrate providing metal coordination centers, by carrying out a controlled chelating reaction and thermal treatment on the substrate surface with a predetermined specific amount (X.sub.o) of tetranitrile compound per unit substrate area. The temperature and duration as well as this specific amount (X.sub.o) are selected from given ranges to form a uniform polychelate coatingbonded to the substrate surface. Titanium electrodes are provided with such polychelate coatings for different purposes. Electrodes with other metal substrates are further provided with such polychelate coatings.
