Abstract
The use of self-lubricating materials not only reduces friction coefficients and alleviates effects of wear and tear, but also helps to maintain the mechanical properties of materials. By using coating technology in the application of self-lubricating materials, it is possible to effectively improve the bonding strength between a solid lubricant and substrate material and additionally to protect the solid lubricant against oxidation and decomposition during the sintering process. This study uses the heterogeneous nucleation method, where aluminum hydroxide (Al(OH)3) is coated on the surface of calcium fluoride (CaF2) to prepare a CaF2@Al(OH)3 composite powder. It was observed, through analysis of the preparation process parameters, that the Al3+ concentration, pH value, and reaction temperature were the factors which most influence coating quality. Optimum process parameters were found to be an Al3+ concentration of 0.15 mol · L–1, pH value of 7.5, and reaction temperature of 75 °C. Comparing and analyzing the micro-morphology of sample composite powders proved the effectiveness and favorable performance of the CaF2@Al(OH)3 composite we produced under optimized process parameters.
