Nuclear
Nuclear facilities demand certified processes, documented procedures and absolute traceability. Brush plating restores precision fits and sealing surfaces on plant components without heat input — critical where hot work is restricted.
Typical components
- Valve seats and stems
- Pump shafts and seal areas
- Control-rod drive components
- Reactor tooling and fixtures
- Heat-exchanger and condenser parts
Why brush plating works here
- No heat-affected zone — safe for use around sensitive plant equipment
- Documented procedures with full material and process traceability
- Portable process brings the repair to the component, not the other way around
End Fitting Leakage Repairs
Canadian Metal-Ad Corporation has a proven repair procedure for End Fitting leakage problems. Selective Electrochemical Deposition Metallizing (SEDM) is the term given to describe the metal addition process of small area plating without the use of immersion. The process is also referred to as Brush Plating or Electrochemical Metallizing (ECM).
Similar in technology to tank electroplating, metal addition SEDM electrolytically deposits a wide range of engineering metals from specially prepared solutions. Due to its pinpoint accuracy in area and thickness, metal addition SEDM often requires no post surface finishing of the deposit. Being a mobile and versatile process, it is the preferred method of metal build-up on parts too large or difficult to disassemble or remove.
Proven In-Service Results
Our technicians have completed repairs inside operating stations around the world — including an E-Face surface repair at Wolsong 2 in South Korea and extensive repairs at the Pickering Nuclear Generating Station in Ontario. In each case, worn and leaking surfaces were restored in place, avoiding the cost and schedule impact of component removal.
