Abstract:
A statistical analysis of the performance of a ceramic bonded solid film lubricant is presented. The ceramic bonded film, PbS/B2O3 in a six to one weight ratio of lubricant to binder, is of interest in the 700 to 1000 F temperature range. Experiments were conducted on the Hohman A-6 tester with two loading shoes. The analysis of variance shows that, within the range of the variables studied, the main effects of bearing load and ambient temperature are significant, and that a response to a change in temperature depends on speed. The results are analyzed with an approximate and with an exact statistical method. The two methods lead to identical conclusions.
