Tribosynthesis of lead fluoride in friction of fluroplastic lead-containing composites and its effect on wear resistance

The processes running in the friction contact zone of lead-containing fluoroplastic composites and steel counterbody are studied. The results of X-ray phase examination of the transfer films on the steel counterbody are presented for the case of friction of lead-fluoride-containing fluroplastic comp...

Summary:The processes running in the friction contact zone of lead-containing fluoroplastic composites and steel counterbody are studied. The results of X-ray phase examination of the transfer films on the steel counterbody are presented for the case of friction of lead-fluoride-containing fluroplastic composites. In friction of the given composites, the secondary structure, namely lead fluoride, is shown to arise in the contact zone. It is found that the fluorite crystalline structure β-PbF 2 possesses lubricity and increases the wear resistance of PTFE-based composites.
