Fungus formation after exposure to Brake Fluids





2003

Sir,

We are manufacturers of Disc Brake systems.We wish to know whether the surfaces in contact with brake fluid are prone to fungus formation when exposed to air. This problem was observed in one of the component. Also let us know whether ultrasonic cleaning during manufacture will avoid this problem.

Dear Mr Prabhu Ram,

It helps to know what is the base material? Aluminium, Copper, Steel ? Also Ultrasonic cleaning with a corrosion inhibitor, or an additional chromating process will help.

Dear Sir,

Thanks for your reply. The base material is Aluminium.(Gravity Die Cast).We do shot blasting. Also we do chromating. Our query is whether ultrasonic cleaning will contribute to avoid fungus formation.

Dear Mr Prabhu,

The Aluminium surface is very active after Shot blasting. I do not see the need for ultrasonic cleaning apart from removal of shots. It is better to try to do the chromating as soon after the shot blasting and minimise handling of the parts in between. Please use a hot caustic free degreaser before chromating.
