For the quantitative treatment of the influence of molecular structure a definition of the “degree of molecular branching” is suggested, and this is tested using measurements by the present authors and others.

ilSME, 1967, IZ pp.; 7 figs., g tables, ro refs. The use of heat-resistant cobalt and nickel alloys in modern technology is rapidly increasing. These alloys, along with the stainless steels, are the materials which fill the need when high strength, corrosion resistance and high temperatures are called for. Laboratory friction experiments show that small amounts of iodine complexes are effective extreme pressure lubricant additives for these materials. Machining tests on an instrumented lathe using these iodine complexes in cutting oils resulted in a marked decrease in tool forces. Processing,

Phenothiazine carboxylic acid esters are more effective antioxidants than phenothiazine on a molar basis in diester oils. No “phenothiazine sludge” occurs with these esters such as is observed with phenothiazine at temperatures above 300°F.

The SNAP 8 reactor bearings are designed to provide low-friction self-lubrication at I 15o’F while in the environment of a nuclear reactor operating in space. A four-phase program is described that has successfully developed these low-speed, oscillating bearings. Phase One was the study and screen testing of static adhesion of bearing materials. Phase Two was the study and screen testing of bearing materials in sliding couple. Phase Three was the application ofthe bearing materials into were bearing designs where prototypes fabricated and tested. And Phase Four was Wear, IO (1967) 410-417
