The sliding behaviour of polyamide-6 (PA6) treated by nitrogen plasma immersion ion implantation (N PIII) has not been studied yet, even if PIII is a promising technique for polymer surface modification. The effect of N PIII of PA6 on its sliding properties against low carbon structural steel S235 was studied. The surface changes were characterised by XPS, contact angle measurements and optical microscopy,...
Polymers are increasingly used in tribological applications, because of their self-lubricating ability, corrosion resistance and chemical compatibility. However, their performance depends strongly on the parameters of the total tribological system. Not only polymer characteristics, but also counterface properties become important because of their influence on friction and wear, on surface energy and...
For economical, ecological and even technical reasons for some years there has been a tendency to introduce self-lubricating materials for bearing applications. In this way external lubricants such as oil or grease can be excluded, the design can be simplified and maintenance cost can be reduced. Among the self-lubricating materials the so-called engineering plastics have increasing importance. Unfortunately,...
The global aim of this project consists of the determination of the sliding properties on small-scale and large-scale polymer samples against steel and DLN coated steel (diamond-like carbon). This was done by the aid of laboratory tests to investigate the tribological behaviour of the various engineering plastics and the optical inspection of the counter faces. With continuous sliding friction, the...
