Abstract
Means are provided for imparting an adherent wear and fatigue-resistant thin surface film on a metal object prior to contact of said object with another surface by the application of dinonylphenyl hydrogen phosphonate to form a surface reaction coating on the metal object.
Claims8
A method for forming an adherent, wear and fatigue resistant, protective film on a surface of a metal object, prior to contact of the object with another metal surface, which comprises:
- a. coating and reacting the surface of the object with a solution of dinonylphenyl hydrogen phosphonate in a non-reactive solvent;
- b. thereafter removing the non-reactive solvent with a solvent in which the non-reactive solvent is soluble;
- and,
- c. drying the metal object after removal of the non-reactive solvent from the surface thereof.
A method for forming an adherent, wear and fatigue resistant, protective film on a surface of a metal object, prior to contact of the object with another metal surface, which comprises:
- a. coating and reacting the surface of the object with dinonylphenyl hydrogen phosphonate alone, and
- b. removing excess dinonylphenyl hydrogen phosphonate from the surface of the object.
