Possible stibnite transformation at the friction surface of the semi-metallic friction composites designed for car brake linings
چکیده انگلیسی

After a friction process several changes in phase composition of friction composites are often registered. High temperature, accompanied by high pressure induced during braking can cause initiation of chemical reactions which do not run at room or elevated temperatures under the atmospheric pressure. Most of the studies in the field of tribochemistry at friction surfaces of automotive semi-metallic brake linings deal with phenolic resin degradation and corrosion of metallic components. The paper addresses the formation of elemental antimony as well as the alloying process of iron with antimony observed on the surface of laboratory prepared semi-metallic friction composites containing stibnite. The role of alumina abrasives in the process of stibnite transformation is also discussed and mechanism of stibnite transformation was outlined.

► Transformation of Sb2S3 in semi-metallic fiction composites for car brake lining. ► Antimony formation during friction process of brake linings. ► Alloying of iron from steel wool by antimony and ɛ-FeSb and FeSb2 formation
