...Haifei Zheng; Yanguo Yin; Rongrong Li; Cong Liu; Qi Chen Purpose This paper aims to investigate the effect of chemical nickel plating and mechanical alloying on the mechanical and tribological properties of FeS/iron-based self-lubricating materials as well as the wear mechanism of the materials...

...–material ratio can excessively weaken the mechanical properties of the material and reduce its wear resistance. Originality/value The effects of ball–material ratio on Cu-Bi mixed powder and material properties were clarified. This work provides a reference for the mechanical alloying process and its...

.../approach The materials were fabricated by mechanical alloying and powder metallurgy and tested under dry friction conditions using HDM-20 wear tester. Findings The results show that mechanical alloying can improve the antifriction and wear resistance of the materials. The 6 per cent FeS and 6 per cent...
