| Popis: | The materials involved in this research study were produced by diemoulding 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 valuesfor theglass beads concentrations were established at 10 % and 20 %(wt).Block‐on‐ring tests were run in order to characterize the tribologicalbehaviour of this friction couple (PBT and PBT composites with glassbeads on steel). The block was manufactured by cutting parts from thebone samples, having the dimensions of 16.5 mm × 10 mm × 4 mm. Theother triboelement was the external ring of the tapered rolling bearing KBS 30202, having dimensions of Ø35 mm × 10 mm and was made ofsteel grade DIN 100Cr6. There were analysed the followingcharacteristics: friction coefficient (mean value over a test andscattering range), wear (wear rate). There are also presented particular aspects oftheworn surfaces, asinvestigated fromSEMimages |
