Özet
İngilizce (OpenAlex)
In this study; brake discs used in vehicles have investigated. The behavior of these discs during braking, wear and braking distance performance of the coated and uncoated surfaces during the braking process were evaluated. The surface of the commercially produced discs was coated with a thickness of 1 mm using the HVOF (High Velocity Oxy-Fuel) coating method. In the coating process CoNiCrAlY, WC-Co (88/12), NiCrBSi and MoNiCrBSiFe (Mo 25%) 4 (four) different ceramic powders were used respectively. Wear and brake distance tests of coated and uncoated discs were performed by braking in a total of 20 brakes in 15 seconds on the brake-suspension tester. After the brake tests, the surface roughness changes of the discs, surface hardness change, mass loss and the abrasion values on the disc surfaces were determined due to the brake force applied to the discs during the experiment. The most wear on the discs was on the CoNiCrAlY ceramic powder coated disc at 0,4 g, while the least wear occurred on the disc coated with NiCrBSi ceramic powder at 0,2 g.
