The wear of LM13 composites supplemented with different weight percentages of carbon and zircon is investigated in this work in relation to contact pressure, sliding speed, sliding distance, and zircon content. To ensure unidirectional solidification, stir casting was used to create the composites, and wear characteristics were assessed at the chill end. The composite containing 9% weight zircon showed the lowest wear rate, according to dry sliding wear testing. In general, wear rose as sliding distance, sliding speed, and contact pressure increased. Zircon content had the biggest impact on wear performance out of all the variables. Analysis of surface morphology revealed delamination and grooves, especially in composites with lower amounts of reinforcement.

摘要

The wear of LM13 composites supplemented with different weight percentages of carbon and zircon is investigated in this work in relation to contact pressure, sliding speed, sliding distance, and zircon content. To ensure unidirectional solidification, stir casting was used to create the composites, and wear characteristics were assessed at the chill end. The composite containing 9% weight zircon showed the lowest wear rate, according to dry sliding wear testing. In general, wear rose as sliding distance, sliding speed, and contact pressure increased. Zircon content had the biggest impact on wear performance out of all the variables. Analysis of surface morphology revealed delamination and grooves, especially in composites with lower amounts of reinforcement.
