SARAS Localised Repair Process
SARAS is a metal plating process that adds metals and alloys to existing components simply and cost effectively. Unlike bath plating the process is selective. Only the areas for treatment are processed and being portable the processing can be carried out on site at clients’ premises or components location.
The components do not have to be stripped down as this is a localised process. SARAS plates only where the electrode touches, therefore little masking is required. It is a cold process, there is no heat and therefore no distortion and it does not cause embrittlement.
We offer a full range of oven capacities for both pre-plate and post-plate heat treatments. Furnace sizes available range from small electric oven up to large gas fired furnace with temperatures up to 1,200°C. A typical heat treatment for diffused nickel, often used on the end fittings for flexible pipe lines, require a furnace main soak of 10 hours at 610°C.
Testing and Reporting
We constantly monitor and test our chemicals and coatings to provide accurate and reliable data regarding material properties. This allows us to validate the integrity of our services and in the process prevent coating related problems occurring. We provide accurate and dependable testing reports to support the various demands of our customers and specification requirements.
In some cases an area or part of a component may be required to be masked off to prevent nickel coating, such as internal or external threads, bores or blind holes due to fitting or service requirements. This can be achieved by various methods including red stopping-off lacquer, plastic and metal tape or fitted bungs. Our team will be able to advise on the best solution for masking after reviewing the component drawing.
