The dynamic evolution mechanism on a friction surface of high temperature gland self-lubricating composite was analyzed based on the micro-structure characteristics of the materials and its tribological experimental results in the pin-disk test. A cellular automaton model to describe the dynamic characteristics of the friction process was developed and used to study the friction coefficient and the topography as well the lubricants distribution on the worn surface in the sliding. The agreement between the simulation and experimental results show the model is available and can be used to optimal design of the materials. 
