| This effect is related to the oxide layer used for passivation of the silicon surface. |
| For example, coronary stents manufactured of 316L-grade stainless steel can undergo a wide range of annealing, passivation, electropolishing, and cleaning processes. |
| A drain electrode layer is formed by a first passivation film with the first passivation film formed as an upper layer. |
| For example, manufacturers should document any bench testing conducted to assess electropolishing or passivation of the stent materials. |
| Chromate passivation systems containing hexavalent chromium compounds are extensively used in electroplating and metal treatment processing. |
| Ecolab also provides passivation programs that help extend the life of installed equipment. |
