运用等离子喷涂技术在铝合金表面制备 TiCP/镍基合金复合涂层，研究干摩擦条件下载荷、速度和温度对复合涂层摩擦磨损行为与机理的影响规律；建立了基于最小二乘支持向量机(LS-SVM)的复合涂层磨损预测模型。结果表明：在不同摩擦条件下，TiCP/镍基合金复合涂层的摩擦因数和磨损质量均低于镍基合金涂层。LS-SVM模型对摩擦因数和磨损失重的预测时间仅为 BP-ANN 模型的12.93%，其预测精度分别比 BP-ANN 模型提高了58.74%和41.87%，可有效预测干摩擦条件下TiCP/镍基合金复合涂层的摩擦磨损行为。

TiC particles reinforced Ni-based alloy composite coatings were prepared on 7005 aluminum alloy by plasma spray. The effects of load, speed and temperature on the tribological behavior and mechanisms of the composite coatings under dry friction were researched. The wear prediction model of the composite coatings was established based on the least square support vector machine (LS-SVM). The results show that the composite coatings exhibit smaller friction coefficients and wear losses than the Ni-based alloy coatings under different friction conditions. The predicting time of the LS-SVM model is only 12.93%of that of the BP-ANN model, and the predicting accuracies on friction coefficients and wear losses of the former are increased by 58.74%and 41.87%compared with the latter. The LS-SVM model can effectively predict the tribological behavior of the TiCP/Ni-base alloy composite coatings under dry friction.
