The influence of nickel-clad chromium carbide on the tribological properties of composite based on phenylone aromatic polyamide

The paper examines the influence of nickel-clad chromium carbide (PKHN-15) on the tribological properties of phenylone C-1 aromatic polyamide under friction conditions without lubrication. It was established that the introduction of a filler in the amount of 10-25 wt.% leads to a decrease in the degree of linear wear of the polymer matrix by almost 15 times, reaching minimum values at 20 wt.% of the filler. The lowest coefficient of friction is observed for the polymer composite containing 10 wt.% PKHN-15. The improvement of the tribotechnical properties of polyamide is due to the fact that harder filler particles strengthen the polymer matrix. As a result, the composites are better able to withstand mechanical loads, micro-impacts and destruction.
