| The unreinforced portion was made of aluminum alloy (Al-2014). Various SiC particles were added to the Al alloy as a reinforcing substance. | Pin-on-disc wear test | With the increase in grain size, weight loss was observed to increase. It was discovered that composites with larger particle sizes had better wear resistance. | [16] |
| AZ91D alloy | Pin-on-disc | Due to the relative motion of AZ91D and stainless steel, frictional heat is generated, which affects the rate of wear. | [17] |
1. Nylon gears
2. Acetal gear pairs | Pin-on-disc | The acetal gear pair has a higher wear rate than the nylon gear pair. Each acetal gear pair has a sliding speed threshold above which the wear rate dramatically increases. | [18] |
| A substrate made of BBS: LM 11 alloys was used, which was reinforced with (a) SiC particles and (b) SiC fibers for producing composites. | Pin-on-disc | The wear rate of the base alloy with no reinforcements was the highest, while the composites had the lowest wear rate. Because of a solid particle-matrix interface, the alloy reinforced with SiC particles had a low wear rate, whereas the alloy reinforced with SiC fibers had a higher wear rate due to a weak fiber-matrix interface. | [19] |

1. 10% B4C
2. 15% B4C
3. 20% B4C
4. 4147 Al/SiC composite | Pin-on-disc | Due to stronger SiC particle binding to the alloy matrix, Al/SiC matrix alloys outperformed AL/B4C alloys in terms of wear resistance. | [21] |

| Ti-6Al-4V alloy without thermal oxidation and Ti-6Al-4V alloy with thermal oxidation | Pin-on-disc | The handled specimen has shallower and thinner wear tracks than the untreated alloy. | [29] |
1. Al-SiC-Gr composites
