Abstract: Abstract. Classical theories state that the friction coefficient is independent of geometry, depending only on the real contact area determined by roughness. However, experimental evidence shows significant differences ...

Abstract: Tribo-oxidation mechanism and tribological behavior of TaC–20 vol%SiC composites from 25 to 800 °C coupled with aluminum oxide (Al2O3) and cemented carbide (WC–Co) were investigated. Tribo-oxidation products on the worn ...
