چکیده انگلیسی
In the present study, the abrasive wear characteristics of Al2O3/PA1010 composite coatings were tested on the turnplate abrasive wear testing machine. Steel 45 (quenched and low-temperature tempered) was used as a reference material. The experimental results showed that when the Al2O3 particles have been treated with a silane coupling agent (γ-aminopropyl-triethoxysilane), the abrasive wear resistance of Al2O3/PA1010 composite coatings has a good linear relationship with the volume fraction of Al2O3 particles in Al2O3/PA1010 composite coatings and the linear correlation coefficient is 0.979. Under the experimental conditions, the size of Al2O3 particles (40.5-161.0 μm) has little influence on the abrasive wear resistance of Al2O3/PA1010 composite coatings. By treating the surface of Al2O3 particles with the silane coupling agent, the distribution of Al2O3 particles in PA1010 matrix is more homogeneous and the bonding state between Al2O3 particles and PA1010 matrix is better. Therefore, the Al2O3 particles make the Al2O3/PA1010 composite coatings have better abrasive wear resistance than PA1010 coating. The wear resistance of Al2O3/PA1010 composite coatings is about 45% compared with that of steel 45.
