Abstract:
BACKGROUND:As a lubricant of artificial organs,lubricant capacity of blood is influenced by many factors,including hematocrit.OBJECTIVE: To explore the effect of hematocrit on blood lubricant capacity．METHODS: The lubricant capacities of four Kinds of hematocrit blood were studied by GB3142-82 lubricants-determination of bearing capacity testing.In addition,the differences of worn spots and the adsorption film formed on the steel ball under different hematocrit blood lubricating were observed by the Leica DMI 5000M material microscope．RESULTS AND CONCLUSION: ①The microshape of the adsorption films was depended on the hematocrit.②The greater hematocrit levels,the smaller worn spots formed on the steel ball,namely,increased hematocrit lead to stronger bearing capacity.
