Definitions

  • This invention relates to compositions having ability of displacing moisture, corrosive materials and the like from corrosive surfaces.
  • This invention also pertains to the formation on such surfaces of a non-corrosive moisture resistant protective film.
  • More particularly thi invention pertains to corrosion inhibiting compositions suitable for protecting metal. and non-metal surfaces by rendering them impervious to water, electrolytic solutions, corrosive fluids, gases, and the like, by displacing said contaminant from said surfaces and forming thereon a tenacious protective film having good lubricating properties.
  • Corrosion of alloyed bearings and other alloyed surfaces due to contact with water can attain such an aggravated stage as to cause great fatigue stresses to be set up, which ultimately result in cracking of the metal.
  • Moisture adhering to pickled steel, quenched steel, equipment such as instruments, engine starters and generators on landing crafts, hydraulic systems, machinery for metal processing and the like are alsoyextremely susceptible to corrosion and must be protected.
  • Rust preventative, water displacing compositions are particularly desired in metal rolling operation such as prior to cold rolling of metals.
  • metal sheets or strips are hot rolled, and then subjected to the following operations:
  • the material After the material has ben subjected to these operations it is cold rolled, generally using, as a lubricant and cooling agent, a soluble oil emulsion. Subsequently, the articles are annealed, and then subjected, if desired, to a light rolling without oil through highly polished rolls.

  • Metal surfaces have positions, waxes, organic compounds, e. g. or-
  • chemical reactive inhibitors are incapable of penetrating the surface being protected and are incapable of displacing the contaminant there from. In cases where such inhibitors are able to form protective coatings on surfaces they are easily displaced by moisture or rupture readily. They are relatively ineffective against corrosive acidic materials and hot gases such asare formed during operation of combustion and turbine engines and are easily destroyed when applied to surfaces which are subjected to high temperatures.
