[Research on stability of hemocompatibility of DLC film/Ti6Al4V gradient material using image analysis method].
The stability of hemocompatibility of Ti6Al4V alloy and DLC film/Ti6Al4V gradient material has been studied. The platelet consumption ratio of Ti6Al4V alloy to DLC film/Ti6Al4V gradient material has been measured respectively by digital image analysis method. It has been found that the platelet consumption ratio of Ti6Al4V alloy increased remarkedly about 50% after 2,000 m sliding tribological test under the lubrication of Hank's solution, while that of DLC film/Ti6Al4V gradient material almost didn't increase under the same condition, which means that the DLC film/Ti6Al4V gradient material has better stability of hemocompatibility.
