In the latter case the anodes are made of insoluble materials, such as titanium coated with iridium oxide. In addition, because zinc tends to oxidize in preference to iron, some protection is afforded the steel surface even if some of it is exposed through cracks. Based on the large differences in molecular properties between the organic surface coatings and the bare zinc oxide properties , it was expected that each group would separate during clustering analysis, as was the case with this data . When the temperature reaches 225°C, zinc oxidizes violently. Ac­cord­ing to var­i­ous the­o­ries, zin­cum can be trans­lat­ed from Latin as “white coat­ing,” while the word “zinke” means “tooth” in Ger­man.
