Abstract :
In order to lengthen the service life of artificial organs ,blood can be used as lubricant in artificial organs.For the purpose of studying on the influenced factors to blood lubricating properties,especially how much the component of blood can affect blood lubricating properties. In this paper, the blood lubricating properties of four kinds of hematocrit were studied by the friction tester. The worn spots and the adsorption films formed on the steel ball were observed through the Leica DMI 5000 M material Microscope. It was found that: (1) the microshape of the lubricant film depends on the hematocrit; (2) the higher blood´s hematocrit is, the smaller worn spots formed on the steel ball become. It is concluded that the higher the hematocrit is, the larger the lubricant film´s bearing capacity appears.
