A Fractional Factorial Design Study of Reciprocating Wear Behavior of Al-Si-SiCp Composites at Lubricated Contacts

摘要: The lubricated reciprocating wear behavior of two composites A319/15%SiCp and A390/15%SiCp produced by the liquid metallurgy route was investigated means an indigenously developed friction test rig using a fractional factorial-design approach. main purpose to study influence parameters such as applied load, sliding distance, velocity, counter surface temperature silicon content in composites, well their interactions on characteristics these composites. Two output responses (wear loss coefficient friction) were measured. input parameter levels fixed through pilot experiment conducted newly rig. material used for cast iron having Vickers hardness 244 HVN. It had been demonstrated established equations that composite is subjected low compared composite. experimental results indicate proposed mathematical models suggested could adequately describe performance indicators within limits factors are being investigated. temperature, five important controlling condition. Moreover, factor have strong effect give comprehensive insight into
