The structure, mechanical and ndcrotribological properties were studied by PHI--5300, FT--IR2000, Xos and atolinc force and frictioll force microscOPe. The results show that the multilayer is consist of crystalline Teflon and amorphous St3N4. The hardness of the multilayer is less than that of St3N4; but the toughness of Teflon/SisN' is greatly approved. This Teflon/Si3N4 multilayer has low friction coefficient and high wear resistance. The friction force of Tellon/ St3N4 film is linear with the load in nano--scale.The worn track will be formed in Teflon film when the load is greater than 70 uN.Keywrods: Teflon, multilayer film, structure, structure ,microtribology Key words:  Teflon      multilayer film      structure      structure       microtribology      Received:  18 June 1998      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1998/V34/I6/655 1 Clegg W J, Kendall K, Alford N M, Button T W, Birchal J D.
