摘要：
Investigation results for a friction pair incorporating a UHMWPE specimen with a microporous surface layer carrying an electret charge and a counterbody of an animal cartilage are presented. Based on the results obtained, theoretical and experimental bases for manufacturing metal-polymer unipolar heads of hip joint endoprostheses have been developed. The experimental results have proved that the modified polymer head of the unipolar hip joint excels the initial one when operated in a human organism.
