| Abstract: | The dry sliding tribological behaviours of plasma sprayed Ni based WC coating are researched,and the relation of wear machanisms of the coating and porosity,microhardness,wear surface topography and the section of the coating are investigated.The experimental results show that Ni based WC coating possesses better tribological behaviours than wear plate,and with the increase in sliding speed,the increase of contact wear rate is less and the decrease of frictional coefficient is larger,and with the increase of contact loads,the decrease of frictional coefficient and the increase of contact wear rate are less. |
