Özet
In this experimental study, polyamide6 polymer, which is among the engineering plastics used in rolling bearings, gears, rollers and bushings, was used. In addition, PA6 polymer blends with 6% wax solid lubricant were produced to increase wear resistance and their tribological performances were investigated. The polyamide 6/wax blend was first produced in granule form in twin screw extruder by compound production method. Then, test specimens were injection molded using the granules. AISI 316L stainless steel was used as a counter-disc in tribology tests. The tests were carried out under dry sliding conditions and at room temperature. Wear tests were carried out on a pin-disc wear tester at two different loads and four different sliding speeds. The coefficient of friction (CoF) and specific wear rate (SWR) of the materials were determined. According to the test results, an increase in the CoF and SWR of both PA6 polymer and PA6/6% wax blend was observed with increasing sliding speed. At the load and speed ranges studied, the CoF of pure PA6 polymer varied between 0.25 and 0.36, while the CoF of PA6/6% wax blend varied between 0.10 and 0.13. The SWR of PA6 polymer was obtained in the range of 1.2-12x10-4 mm3/N-1m-1, while the SWR of PA6/6% wax blend was obtained in the range of 1.2-3.0x10-5 mm3/N-1m-1. The addition of 6% wax to PA6 polymer caused a significant decrease in both CoF and SWR and contact surface temperature.
