Steel-based copper graphite self-lubricating plate

The utility model belongs to the technical field of graphite self-lubricating plates, and particularly relates to a steel-based copper graphite self-lubricating plate which comprises a copper alloy graphite layer, a steel-based plate layer and a transition layer. The copper alloy graphite layer is a working layer and has a self-lubricating effect; the steel-based plate layer is the bottommost layer of the steel-based copper graphite self-lubricating plate; the transition layer is arranged between the copper alloy graphite layer and the steel substrate layer and used for connecting the copper alloy graphite layer and the steel substrate layer. According to the steel-based copper graphite self-lubricating plate, the transition layer is additionally arranged between the steel-based plate layer and the copper alloy graphite layer, so that the integrity and the stability of the steel-based copper graphite self-lubricating plate can be ensured, and the service life is prolonged. 本实用新型属于石墨自润滑板技术领域，尤其涉及一种钢基铜石墨自润滑板，包括
