英文摘要	For exploring the possibility of a. hybrid mode With smooth transition from fluid to boundary even to solid lubrication at the elevated temperature, i.e., searching a substance which should be the solid lubricant. and oil additive with environmentally friendly. characters; a Series of perrhenates (the soft double oxide) were synthesized as the candidates because of their crystalline and decomposed products with a good anti-friction behaviour, such a Re(2)O(7) which might provide the lubrication during Oil decomposition for its good sublimation kit about. 300 degrees C. This investigation might, be advantage of lubrication for rubbing part's of internal combustion or turbo engine such as piston ring and cylinder liner or exchanger; which were always operated in a. cyclical variation of temperature (even to 800 degrees C). In this paper, the properties of perrhenates of Fe, Co, Ni, Cu, Pb, Ca, Ba and La synthesized by aqua-solution method were described and their crystalline structures, compositions and morphologies were determined by XRD, SEM-EDS For understanding their lubricating behaviors in both dry sliding base oil pentaerythritol ester (PETE), their lubricating behaviors between Si(3)N(4) ball and superalloy disc were tested in pin-on-disc Oil universal micro-tribotester (UMT-2) from 20 to 750 degrees C. The results show that most synthesized perrhenates ale crystal powder except the synthesized gel-like ferric perrhenate, their crystalline structures are coincidence with powder diffraction file (PDF) cards, and compositions are very close to the stoichiometic values Some of the synthesized perrhenates exhibit certain lubrication at 300-750 degrees C, in both dry sliding and oil lubrication With addition of the synthesized perrhenate which were verified in reciprocating sliding The variation of friction coefficients temperature probably results from the formation or removal of soft oxides at, high temperature The good anti-frictional behaviors of the synthesized perrhenates of Ca, Co and Cu in a, wide temperature range seem to imply. them to be developed as the candidates of additive in a hybrid lubricating mode for the engine operating in cyclical variation of temperature.
