本工作描述了原位Al-4.5%Cu/x TiC（其中x=5%， 7%和10% (wt%)）金属基复合材料的全因子实验磨料磨损模型设计。在针盘式装置上对复合材料进行了磨损试验，并在圆盘上固定了600粒SiC砂纸。控制因素为外加载荷、滑动距离和TiC增强剂在金属基体中的重量%。从主效应图中可以看出，滑动距离对减重的影响相对高于外加载荷和TiC的重量%。此外，载荷/滑动距离的交互作用对减重有显著影响。还观察到，随着滑动距离的增加，摩擦系数增大。基于相互作用的显著性，推导了回归方程，并用多个测试用例进一步验证了模型的充分性。对该工艺进行了多响应优化，验证性试验表明，该模型的准确度在+/- 2.57%以内。(C) 2013 Elsevier B.V.版权所有
The present work describes the full factorial design of experiment based abrasive wear modeling of in-situ Al-4.5%Cu/x TiC (where x=5%, 7% and 10% (wt%)) metal matrix composites. The composites were wear tested on a pin-on-disk apparatus in which 600 grit SiC abrasive paper was fixed on the disk. The control factors were the applied load, sliding distance and weight% of TiC reinforcement in the metal matrix. It has been observed from the main effect plots that the significance of sliding distance on weight loss is relatively higher than the applied load and weight% of TiC. Moreover, the interaction of load/sliding distance indicated significant effect on weight loss. It has also been observed that with a rise in the sliding distance coefficient of friction increased. Based on the significance of interactions, the regression equations were derived and verified further with a number of test cases to assess the adequacy of the model. Multi-response optimization of the process was also done and confirmatory tests revealed the accuracy of the model within +/- 2.57%. (C) 2013 Elsevier B.V. All rights reserved.
