Flash Chrome Plating

We offer a flash chrome plating service based on Chromic Acid - Chromium Trioxide Flake from Elementis. Our solution is made up of 250g/l CrO3 and Sulphuric Acid at a 100:1 ratio.

Process: Flash hard chrome plating is an electrolytic process utilising a chromic acid-based electrolyte. The component requiring plating becomes the cathode and, with the passage of a DC current via anodes, chromium metal builds on the component surface.

Background: Flash hard chrome plating, also referred to as functional chrome plating, is applied as a thinner layer. It is ideal for close tolerance applications where an excessive build up of chrome is undesirable and where the requirement is to provide a durable hard wear-resisting surface.

Applications: Flash Hard Chrome plating has many typical applications, some of which are detailed below:

  • Wire wound rods for paper coating
  • Seal areas on pump or drive shafts
  • Conveyer guide rails and rollers
  • Plastic extruder screws
  • Hydraulic rams and cylinders
  • Print rollers

Tanks: We offer tank sizes up to 3.6m long.

Thickness: Coating thickness is dependent on the application and the customers’ requirements, which can normally range from 10 to 25 microns. This smaller deposit of hard chrome usually eliminates the need for a grinding operation to finish.

Hardness: Hardness is in the region of 950 - 1150HV.

Materials: Most materials can be Flash Chrome plated, including:

  • Steel
  • Stainless Steel
  • Cast Iron
  • Copper
  • Brass
  • Bronze Alloys
  • Nickel Alloys

Plating Vats: We have the capacity to chrome up to 3.6metres in length and if you think you may have a possible application for a component not listed, please contact us to discuss this further.

Stopping Off: Selective Hard Chrome plating can be achieved through masking with clamca wax or stopping-off lacquer.

Etching: Etching is carried in accordance with the guidance relevant to the base material being plated. All components are etched before Hard Chrome plating to provide a good key for the hard chrome deposit to be applied.

Jigging: Careful jigging is required for hard chrome plating, taking into consideration current carrying capacity and weight of component. Special attention is necessary for the plating of internal surfaces. One of the characteristics of hard chrome is its poor throwing power, therefore auxiliary anodes maybe required at strategic locations.
