摘要： The present invention relates to a Z-type heterojunction photoanode film used for the photocathode protection of a reinforcing bar, the preparation method thereof and a method for the corrosion inhibition of mental materials from concrete structures in marine engineering by using the Z-type heterojunction photoanode film used for the photocathode protection of a reinforcing bar. The preparation method includes steps of preparing Fe2O3 on the conducting surface of a clean conductive substrate through the hydrothermal process, preparing Fe2O3-PANI composite photoanode film by depositing polyaniline on the surface of Fe2O3 through the electrochemical synthesis and preparing Ru-Fe2O3-PANI composite photoanode film on the surface of the Fe2O3-PANI composite photoanode film through the in situ chemical reduction method. The technical solution in the present invention can achieve highly effective photocathode protection of a reinforcing bar from concretes in marine engineering and improve the durability of concrete structures in marine engineering.

摘要： Provided is a system and method for preventing the chemical redox reaction, and thereby, corrosion between potable water and copper piping systems, which causes pinhole leaks in the copper piping systems. A sacrificial anode, made of a material, such as a metal or metal alloy less noble than copper, e.g., iron, zinc, aluminum, magnesium, titanium, and/or alloys thereof, is electrically attached to the potable water copper piping system. Alternatively an active cathodic corrosion prevention system may be used. The active cathodic corrosion protection system is composed of an independent source of DC power, a voltage controller and a non-sacrificial grounding anode. The negative terminal of the voltage controller is connected to the potable water copper piping system. The system is maintained at a voltage and/or potential above the reduction potential of copper.

摘要： Mixed-metal-oxide (MMO) coated precious-metal tape is installed directly on concrete surfaces using an electrically conductive adhesive, thereby obviating the need for slots, holes, cementitious grout or additional concrete. The electrically conductive adhesive is preferably formed by disposing mixed-metal-oxide (MMO) coated precious-metal particles in an adhesive layer. The tape anodes may be installed on the concrete surfaces including a shallow concrete cover or congested reinforcing steel without developing an electrical short circuit between the anode and the reinforcing steel. Overall the invention provides for quick and low cost installation on many concrete structures. Interconnections between the tape anodes and bare metal distribution elements may be made with conductive adhesive or spot welding.

摘要： A dendritic ice crystallizer having a mercury wetted surface (14) from which heat is extracted while the mercury wetted surface is in contact with water at the freezing temperature. The mercury wetted surface can be protect from ionization or corrosion by a cathodic protection means (68). In addition, new or recycled mercury can be used to displace old mercury on the mercury wetted surface (56) in situ by inclining the mercury wetted surface from the horizontal and depositing mercury from a mercury nozzle (60) to the high end of the mercury wetted surface and collecting displaced mercury with a mercury collector (62) at the low end of the mercury wetted surface.

摘要： An anode assembly and method for installing it in a cathodic protection system for an aboveground storage tank is disclosed. The anode assembly basically comprises an elongated electrically conductive anode, a fabric housing and sand backfill. The fabric housing is a hollow member in which the sand is located and through which the anode extends. The anode includes portions extending out of the housing for connection to the cathodic protection system. The anode assembly is arranged to be installed on a flat prepared surface below the bottom of the storage tank, whereupon the anode assembly's weight hold it flat on that surface without the need for staking or other means to hold the assembly flat. The ground with the anode assembly can then be backfilled to the level of the bottom of the storage tank.
