A method of manufacturing a friction article (42) wherein through a series of steps a chrome-zinc-phosphate coating applied to a ferrous based backing plate (10) enhances a resin bond through which a pad (36) of friction material is attached thereto. After the pad (36) of friction material is bonded to the ferrous based backing plate (10), the series of steps are repeated to create an additional chrome-zinc-phosphate coating on this structure to produce a water insoluble coating. Thereafter a lacquer is applied on the structure (42) to seal the coating from the atmosphere. |
