Metallurgical Investigation – Automotive Brake Pad Backplate
REQUIREMENT
The client was concerned by the possible presence of an oxide layer on the surface of an automotive brake pad backplate material. This may affect the adhesion of the friction material to the plates during service.
PROJECT ACTIVITIES
A metallurgical investigation involving Light optical microscopy (LOM) and scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS) was carried out.
FINDINGS
The investigation determined that not all of the surface oxide had been removed during the pickling and shotblasting processes.
- The scale remaining on the surface of the backplate was found to be less than 10 microns thick and well adhered to the plate surface.
- The scale was predominately the oxide phase, fayalite identified by the silicon content found within the scale.
- Some areas of magnetite and haematite were noted. This may affect the adhesion of friction material to the plates during service.
