Abstract:

This report deals with the efforts expended in a 14-month program to develop a corrosion-resistant hard coating and a solid lubricant top coat. The objective of these coatings was to afford hydraulic control actuator roller bearings corrosion resistance for a 10-year storage life and to allow bearing operation for 1000 seconds with an applied load of 31,581 Newtons 7100 lbs over a temperature range of -54 deg C to 316 deg C -65 deg F to 600 deg F. By the use of exposure to aggressive chemical media, candidate ceramic hardcoat materials were evaluated, leading to the use of nichrome and titanium carbide in a two-layer structure. Similar exposure testing of sputtered lubricants led to the use of a molybdenum disulfide - antimony trioxide mixture. Additional solid lubricants based on the results of Part I of this report were used. Self-lubricating composite rollers were fabricated from stretched carbon fiber reinforced thermid 600 containing the GaInWSe2 Westinghouse compact.
