WEAR RESISTANCE IMPROVED CHAIN AND A METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a method for producing a link chain consists in assembling several chain links (39; 40) comprising chain pins (41) or brackets provided with coatings applied by means a PVD (physical vapour deposition) process. Said coatings consist of sliding substance layers or hard and sliding substance layers. A transition area (La; 4) between elements (42; 41) connectable to each other in such a way that the chain links are formed can be devoid of a sliding substance coating.
