when your part made of metal and looses microns, hardness or require any surface treatment, the electrochemical plating process for Repair or Protection must be on top of selection list to be implemented for this job.
The process could be implemented using variety of material (Hard and soft ones), also could be selective on client site or merging in our workshop.
The process used globally for centuries and well known by the name of (chroming) as the most famous material hired for surface treatment.
Interra is able to support its clients with all requirements to refurbish its equipment using our unique selective plating tools, material made by the initiative globally of the process DALIC.
Interra acquired DALIC technology which allows the plating of any type of metal locally onto metal substrates (such as steel, stainless steel, aluminum, copper, chrome , etc.). Selective plating is a process without immersion (unlike bath treatments), in which an anodic tool saturated with electrolyte is electroplated on the part due to the applied current.
DALIC technology is accomplished without any immersion of the part, unlike surface treatments in a bath.
Anodic tools* are impregnated with electrolytes and then brushed on the area to be treated. With the current supplied by a generator, the metal in liquid form will become embedded in the piece in solid form.
The parameters of the generator (amperage, voltage, current quantity) are modified according to each treatment. A cathode device will be used during anodizing on aluminum or titanium alloys.
The advantages of selective plating
Selective plating : We only treat the area(s) that need(s) to be treated
Cold process : No deformations created by heat
Dalic process can be directly applied without dismounting the parts (ex: AOG’s plating jobs on landing gears)
Selective plating devices are transportable anywhere : easy to intervene quickly
Treatment on integrated parts
Flexibility : you can do many different metal platings with the same equipment
Restore geometry of the part without machining
Control of thicknesses : you can deposit from very few microns to hundreds of microns.
The aim of selective plating:
Our coatings aim to repair or bring a new function to a metal part. Here are the most common applications:
Protect against corrosion
Restore functional dimensions of the part
Ensure conductive contact
Obtain a hardness
Fill a hole, an impact
Prevent electrochemical corrosion (galvanic couple)
Anti-fretting/EMC (electromagnetic compatibility), etc.
Improve aesthetic appearance
Areas Of Application:
Crank Shafts, Rotors, Pistons & Rods, Rail way traction motor, rail way wagon shaft, turbine blades, turbine shafts, compressor parts, valves parts, press houses printing cylinders, 13Cr VAM/Tenaris, Hunt, etc... connections for anti galling, others
Interra is certified as DALIC applicator also as VAM copper plating process.
