摘要
Abstract
Alumina particles were codeposited successfully with Al from a room temperature ionic liquid AlCl3-EMIC containing 10 g/L of Al2O3 particles for the first time.It is found that a stable suspension can be obtained when Al2O3 particles were introduced in the acidic AlCl3-EMIC bath.Scanning electron microscopy（SEM） observations on the morphologies of the coatings show that Al2O3 particles are uniformly distributed in the Al matrix.Hardness of Al-Al2O3 composite coating is higher than that of the pure Al coating.Moreover,hardness of the pure Al coatings increases with increasing current density;whilst that of the Al-Al2O3 composite coating decreases with increasing current density.Dispersion mechanism of Al2O3 particles in AlCl3-EMIC and possible codeposition process of the Al and Al2O3 were discussed in detail.关键词
