Polyamide 12 (PA12) and its composite with nanometersized silica (PA12/n-SiO2) coatings were prepared by the flame spraying processThe thermal behavior
mechanical and tribological properties of the coatings were investigated with differential scanning calorimeter (DSC)
electronic tensile testing machine and wear-test machine of MRH-3Fourier transform infrared spectroscopy (FTIR) was used to characterize polymer degradationThe FTIR analysis did not reveal the presence of any oxidation or degradation during the processingThe results showed that the addition of nano-SiO2 could increase the crystallinity
improve the mechanical properties of the coatings and reduce friction and wear of pure polyamide 12 effectivelyIn addition
the nanocomposite coating containing 1.5%(mass) nanometersized silica displayed better properties
