Tribological Characterisation of PBT + Glass Bead Composites with the Help of Block-on-Ring Test
Journal Title: Tribology in Industry - Year 2013, Vol 35, Issue 2
Abstract
The materials involved in this research study were produced by die moulding in order to obtain bone samples type 1A (SR EN ISO 527‐ 2:2003). These composites have a matrix of polybutylene terephthalate (PBT) commercial grade Crastin 6130NC010,DuPont. The values for the glass beads concentrations were established at 10 % and 20 %(wt). Block‐on‐ring tests were run in order to characterize the tribological behaviour of this friction couple (PBT and PBT composites with glass beads on steel). The block was manufactured by cutting parts from the bone samples, having the dimensions of 16.5 mm × 10 mm × 4 mm. The other triboelement was the external ring of the tapered rolling bearing KBS 30202, having dimensions of Ø35 mm × 10 mm and was made of steel grade DIN 100Cr6. There were analysed the following characteristics: friction coefficient (mean value over a test and scattering range), wear (wear rate). There are also presented particular aspects oftheworn surfaces, asinvestigated fromSEMimages.
