Claims
- 1. A method of heat treating fabrication metal parts comprising the steps of:
- heating the parts to a temperature above metallurgical transformation range;
- placing the parts in a heated agitated quench bath comprising a mixture of two organic rust inhibitors, equaling a first weight percentage and a high molecular weight polymer equaling a second weight percentage which is less than the first weight percentage and the balance water ;
- removing the parts from the bath;
- allowing the parts to dry for a period of time up to three weeks; and,
- rinsing the dried parts in water to remove the dried polymer and rust inhibitor therefrom, whereby the presence of the organic rust inhibitors allows for ready rinsing of the parts to remove the polymer.
- 2. A method as defined in claim 1 wherein the polymer is polyvinylpyrrolidone.
- 3. A method as defined in claim 1 wherein the step of washing the parts comprises washing the parts with a power spray having a pressure in the range of about 20 to 40 psi.
- 4. A method as defined in claim 1 wherein the organic rust inhibitor consists of about fifty percent of a diethanolamine of an aliphatic carboxylic acid in which the oxygenated portion can be either aliphatic or aromatic and about fifty percent triethanolamine.
