More Details: Reasonable matching can improve the service life of the friction pair of tire active molds, but there is a lack of research on the matching of tire active molds under actual friction conditions.In view of this situation,a study was conducted to provide guidance for the rational selection of friction pairs for tire active molds.To simulate the actual friction conditions of tire active molds,test equipment was independently developed.Laser quenching test blocks, Ni-P alloy test blocks and QPQ (nitrogen-carbon-oxygen composite treatment technology) test blocks were respectively employed to be paired with the copper-graphite self-lubricating material.Additionally, the friction coefficient, wear loss,morphology and composition of the worn surface and debris of the three groups of friction pairs were compared, and the mechanism of friction and wear was explained.Results showed that when paired with copper-graphite self-lubricating material, the friction coefficient curves of laser quenching test block and QPQ test block were gentle and stable,while the friction coefficient curve of Ni-P alloy test block had a large fluctuation range.Moreover, the order of the average friction coefficient from small to large was laser quenching test block < Ni-P alloy test block
