Lubricating properties of the lubricant is generally evaluated by the friction and wear testing machine. In this paper, by using Four-ball test machine to measure the maximum non-card bite load value (PB), wear scar diameter (WSD) and Pd1.0, Pd2.0 value. The uniform design of experiments is firstly used for arranging multi-level and multi-factor experiments. The stepwise technique is adopted to put forward the regression equation. The compatibility of Nano-ceramic and T106 both additives is studied by a series of tests to improve the efficiency of use of lubricants.
