英文摘要: The purpose of the proposal is to investigate the synergistic mechanism between antifriction and infiltration performance of lubricating alloy using the phase theory and to prepare a new type lubricating coatings with inner gradient structure based on the permeability of porous cermet matrix. With porous cermet as matrix and soft metal alloy as lubricant, the preparation technique and lubricating control mechanism of the coatings will be discussed based on the phase theory of alloy. The research involves: 1. The composition design theory of multiple lubricating alloy with the cooperation of antifriction and infiltration properties. 2. The distribution of lubrication element in the coatings and its preparation control techniques. 3. The thermal diffusion kinetic theory of lubricating elements in the friction process. 4. The lubricating film formation mechanism and lubrication control theory of the inner gradient lubrication coatings. The research will reveal the coupling mechanism between antifriction and infiltration activation functions of lubricating alloy. The preparation technology of lubrication coatings and its lubricating control theory will be innovated. The research will provide a new type lubrication coating material and preparation technology for the elements work at the high temperature condition.
