ABSTRACT:
The invention relates to the coating of steel articles with organic polymeric material for the prevention of wear and corrosion. To obtain secure and permanent adhesion of the coating on the steel article the coating material is compounded so as to result in graft polymerization with the underlying steel face. Fillers may be included in the coating material for enhancing physical characteristics of strength, wear resistance etc., and a preferred coating material includes monomer having functional groups to interact both with the steel substrate and with the fillers. The coating material may be compounded so as to have flow characteristics, before curing, which permit a smooth and finished exposed face to be obtained, particularly on a rough or unfinished steel substrate surface. The coating process is particularly advantageous in the field of steel automative parts exposed to corrosive environments, for example ball studs.
