Surface Review and Letters

Tribological behavior is examined on a reciprocating ball-on-plate tribometer The results indicate that tungsten carbide may be formed between tungsten particles and diamond coating The W–WC–amorphous carbon–diamond structural coating can validly inhibit the crack propagation and decrease the friction coefficient

In this paper Al 2 O 3 /7075 composites were prepared by mechanical alloying with subsequent hot-pressing sintering and the effect of Al 2 O 3 nanoparticle on the mechanical and tribological behavior of 7075 was studied The mechanical property results showed that the hardness and compressive strength of Al 2 O 3 /7075 composites first increased and then decreased with Al 2 O 3 amount
