Sintered Metal Products

Powder metallurgy (PM) in the production of near net shape, intricate components has been available for many years.  Howerver, due to the limitations of PM processing, components have a tendency towards porosity, restricting the type of corrossion protection available to coat these products.

The chemicals involved in the elctroplating process, for example, would be absorbed into the pores and then leach out following the process to attack both the base material and the coating.

Sherardizing, however, is a hot diffusion process which forms a uniform deposit over the whole surface of even irregular shaped articles, sealing the surface pores, thus creating and ideal method of protection fro PM components.
