Abstract

The purpose of this study is to investigate the effects of process parameters on adhesive wear resistance by using the Taguchi experimental design method. In this study, Cu-Ni/B₄C_p composites were produced by the powder metallurgy method and the effect on the adhesive wear resistance was investigated. Cu-Ni/B₄C_p composite materials were made by cold pressing methods and reinforced with 1% Ni as well as with 6, 12 and 18% B₄C_p, respectively. The sintering was carried out at 800 and 900°C for 60 minutes. The wear tests were performed by using block on ring test apparatus at loads of 5, 10 and 15 N at a rotation speed of 90 rpm and a wear distance of 250, 500 and 750 m, respectively. The results were evaluated by the calculated wear losses. The wear resistance increased with increasing B₄C ratio.

Kurzfassung

Das Ziel der diesem Beitrag zugrunde liegenden Studie bestand darin, die Wirkung der Prozessparameter auf den Adhäsionsverschleißwiderstand mittels der Taguchi-Methode für die Gestaltung von Experimenten zu untersuchen. In der Studie wurden Cu-Ni/B₄C_p-Komposite mittels Pulvermetallurgie hergestellt. Die Cu-Ni/B₄C_p-Kompositwerkstoffe wurden mittels Kaltpressmethode hergestellt und mit 1% Ni sowie 6, 12 und 18% B₄C_p verstärkt. Das Sintern wurde bei 800 und 900 °C über 60 min durchgeführt. Die Verschleißversuche wurden mittels einer Block-auf-Ring-Apparatur durchgeführt und zwar bei Kräften von 5, 10 und 15 N bei einer Rotationsgeschwindigkeit von 90 U × min⁻¹ und einer Verschleißdistanz von 250, 500 und 750 m. Die Ergebnisse wurden anhand der berechneten Verschleißverluste bewertet. Der Verschleißwiderstand stieg mit zunehmenden B₄C-Anteil an.
