| Abstract: | Polymer and polymer/ceramic composite coatings were produced by ball-milling 60 μm Nylon-
11 together with nominal 10 vol.% of nano and multi-scale ceramic reinforcements and HVOF
spraying these composite feedstocks onto steel substrates to produce semi-crystalline micron and
nano-scale reinforced coatings polymer matrix composites. Room temperature dry sliding wear
performance of pure Nylon-11, Nylon-11 reinforced with 7 nm silica, and multi-scale Nylon-
11/silica composite coatings incorporating 7-40 nm and 10 μm ceramic particles was
characterized using a pin-on-disk tribometer. Coefficient of friction and wear rate were
determined as a function of applied load and coating composition. Surface profilometry and
scanning electron microscopy were used to characterize and analyze the coatings and wear scars.
The pure Nylon-11 coating experienced less wear than the composites due to the occurrence of
two additional wear mechanisms: abrasive and fatigue wear. |
