摘要

This study investigates, through wear testing, the potential for carburized and tufftrided surface treated steels and the TiN, CrN and TiN + CrN physical vapor deposited (PVD) surface treatments to be used in the screw and rollers of the variable lead screw transmission mechanism (VLSTM). Indentation test results reveal that the thicker the PVD CrN coating, the lower is its adhesive strength, with the desired coating thickness being 10 μm. In general, all sliding pairs possess the best wear resistance under cutting fluid lubrication. Surface treated steels (upper moving specimen) paired with PVD coated parts possess very poor wear resistance under base oil lubrication, even worse than under dry wear. Suitable sliding pairs for VLSTM applications include: surface treated steels paired with either SKH51 or PVD coated specimens under cutting fluid lubrication; PVD coated specimens paired with SKH51 specimens under cutting fluid lubrication; and PVD coated specimens paired with PVD coated specimens under base oil and cutting fluid lubrication.
