Definitions

  • the non-alloy steel is preferably one which contains up to 0.5 wt96 carbon.
  • the performance of the samples was evaluated by measuring the degree of creep of corrosion from two diagonal lines scratched through the organic coating in the form of a cross. The creep was checked by applying 710 tape manufactured by the 3 M's Company over the diagonal lines and then removing it by pulling back rapidly at 180 degrees to the sample surface. Pass or failure judgements were made using a permissible creep value of 2 mm on either side of the diagonal lines.
  • pretreatment of the steel samples according to the present invention produces a substantial improvement in corrosion resistance under salt spray conditions. Accordingly, the present invention is considered to be particularly suitable for steel articles for under bonnet motor vehicle applications. It will be appreciated that salting of roads during the winter time makes it necessary for exposed parts of the vehicle which are formed of steel to be rendered resistant to salt spray corrosion as effectively as possible.
