Problems solved by technology

However, over the past decade, it has been demonstrated that there are self-generated electrochemical potential fluctuations, corrosion-related "electrochemical noise"
As a result, even though Zn / O 2 The potential can be in the switching region, but it is also likely to fluctuate, exciting the potential difference to the highly conductive region and allowing the flow of electrons so that the zinc oxidizes

Embodiment Construction

[0059] The present invention provides a corrosion noise reduction system having an electronic control unit (ECU), a controllable filter and a semiconductor coating on a substrate.

[0060] Figure 8 is a circuit diagram of a specific embodiment of the invention in which components similar to those of Figure 6 retain their previous designations. As shown, the ECU 897 includes a controllable filter 898 and an ECU control circuit 899 . The ECU 897 is optionally connected to one or more local sensors 882, and / or is connected to or contains an antenna (eg, for wireless communication) 881 or other means for enabling wireless communication, such as an optical transceiver. The ECU can also access data stored in a local data archive (not shown) or remotely via an antenna 881, other wireless communication means, or even a wired connection such as a network. The ECU control circuit 899 is arranged to change the filter characteristic curve of the controllable filter 898 so as to change ...

Abstract

An apparatus, system, method and computer program product aimed at controlling the corrosion of conductive structures in contact with a corrosive environment and coated with a semiconductive coating. Wherein the erosion is controlled by a controllable filter (898) and a corresponding electronic control unit (899) arranged to process at least one stored or measured parameter.

Description

[0001] Cross-reference related patent literature [0002] This application is related to US Patent No. 6,325,915, US Patent No. 6,402,933, and pending US Application Serial No. 09 / 887,024, filed June 25, 2001, each of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to control devices, systems and methods for controlling semiconductor-based anti-corrosion and anti-pollution systems. Background technique [0004] According to a report titled "Economic Effects of Metallic Corrosion in the United States" published in 1995 by Battelle and the North American Specialty Steel Industry, the cost of metal corrosion in the U.S. economy is approximately $300 billion per year, cited here. All content is for reference only. The report estimates that approximately one-third of corrosion costs ($100 billion) could be avoided and saved through the widespread use of corrosion-resistant materials and best-in-class corrosion pro...
