Brush plating, also known as selective plating or spot-plating, makes it possible to deposit metals and/or alloys on conducting materials. It is now an integral part of the manufacturing process for many industries.
Brush plating is a turn-key engineered system of electroplating.
Specialized plating (L.D.C.) covering high speed Nickel, Cobalt, Chrome and many other types of materials.
Advantages of Brush Plating
– Mobile service that can be performed anywhere
– Ease of operation
– Faster method for small, localized areas
– Ideal for large parts not suited to immersion baths
– Capability for very rapid metal build-up
– Disassembly of machinery/parts minimized
– Reduces amount of masking required as with bath electroplating
– Reduces high chemical volumes needed for immersion plating
– 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 re-plate the entire part
– Reduces waste disposal problems since minimal volumes of waste are involved
– Reduces overall utility expenses and requires less electrical power
– Compliance with most Federal (US) and Commercial Specifications
– Brush Plating can deposit 16 standard metals and an unlimited number of alloys onto almost any base metal or alloy
What is Brush Plating?
Brush plating is an electrochemical process that uses systems to electroplate, anodize, and electro-polish localized areas on both OEM components and parts that need coatings for repair and dimensional restoration.
Brush systems are portable. Unlike their tank counterparts, brush plating systems use very small volumes of solution and hand-held tools to apply the deposits and coatings onto localized areas. These hand-held tools are covered with an absorbent material that is saturated with a solution and then brushed or rubbed against the part. Brush plating requires different hand-held tools for each different solution in the operation.
A portable power pack provides the direct current required for all the processes. The power pack has at least two leads. One is connected to the tool and the other is connected to the part. The direct current supplied by the power pack is used in a circuit that is completed when the tool is touching the work surface.
The work surface is prepared using the same types of tooling and equipment that are used for the final finishing operation. As with a tank plating process, brush plating requires good preparation of the work surface to produce an adherent deposit.
