SIFCO Brush plating is also known as selective plating, portable electroplating, electrochemical metalizing, and swab plating to name a few.
No matter what you call it, the theory of Brush Plating is simple. It is a portable process whereby metal is deposited from a water based solution onto a metal part, in selective areas, creating an electrochemical bond.
Brush Plating is a turn-key engineered system of electroplating. Originally developed as a quick touch-up tool to correct Bath Plating defects. Brush Plating is now an integral part of the manufacturing process for many industries.
The SIFCO Process currently offers more than a dozen standard metal solutions, as well as numerous alloys. The turn-key system consists of a power supply, plating handles, plating anodes, anode wraps, pumping and heating systems, and operator training aides.
WHY USE BRUSH PLATING?
Flexibility and versatility. You can use this portable process virtually anywhere in the shop or out in the field. It can be taken right to the job site to perform operations such as plating nickel onto localized areas of the international space station, touching up defective cadmium on aircraft landing gear, resizing worn stamping equipment, crankshaft bearing diameters, and repairing scores and pits in the valve stems at nuclear power plants.
ADVANTAGES OF BRUSH PLATING
Brush Plating should be considered whenever industry builds metals for repair or resizing, or for mechanical or corrosion resistant properties. The plater can take equipment used in brush plating to the work, often avoiding disassembly, reassembly, and downtime. Brush plating, or selective plating as it is also known, affords numerous benefits over other metal repair processes such as welding, thermal spraying, or bath electroplating including:
• Portability, the ability to move the equipment to the work rather than the work to outside vendors
• Ease of operation
• Capability for very rapid metal build-up
• Disassembly of machinery/parts minimized
• Reduces amount of masking required as with bath electroplating
• Permits plating of parts too large for normal plating tanks
• The ability to coat to size with little or no post-machining in most cases
• Excellent adhesion to most base materials
• Dense coatings
• Minimization of hydrogen embrittlement
• The ability to add metal without thermal distortion
• Thickness control from 0.00001" (0.25 microns)
• Touch-up of plated coatings without need to strip and replate the entire part
• Reduces waste disposal problems since minimal volumes of waste are involved
• Brush Plating can deposit 16 standard metals and an
• unlimited number of alloys onto almost any base metal or alloy
• Compliance with most Federal (US) and Commercial Specifications
