Problems solved by technology

PTFE itself has disadvantages such as low hardness, high wear rate, and poor bearing capacity.
The plastic layer is too thick, and the composite material has good friction performance under working conditions, but the PTFE on the surface layer is worn away a lot, and the hardness of the workpiece surface is insufficient; without the plastic layer, the copper powder will be exposed, and its surface hardness is close to The hardness of steel, but the friction coefficient is high; the plastic layer is too thin, and the copper powder layer will be exposed under the condition of heavy work wear, especially when subjected to vibration and impact, which also reduces the friction performance of the composite material

Abstract

The invention discloses a production process for an HS311 steel-based copper plastic self-lubrication material. The production process specifically comprises the following steps of blanking, copper powder plate sintering, burdening, liquid formation, sintering and finish rolling. The production process has the beneficial effects that a PTFE steel-based copper plastic composite material has the advantages of the self-lubrication property, good weathering resistance, high(low)-temperature resistance, pollution resistance and the like of common solid lubrication materials, and further has the outstanding advantages of being long in life and high in bearing capacity. The PTFE steel-based copper plastic composite material is suitable for vibration and impact load occasions. The PTFE steel-based copper plastic composite material can also be directly machined into a standard part, and usage is convenient.

Description

technical field [0001] The invention relates to a steel-based copper-plastic self-lubricating wear-resistant engineering material, in particular to a production process of an HS311 steel-based copper-plastic self-lubricating material. Background technique [0002] At present, HS311 steel-based copper-plastic self-lubricating composite material is an engineering material whose mechanical properties depend on the metal base material, while self-lubricating properties depend on the surface plastic. The composite materials used in the existing ordinary steel-based copper-plastic self-lubricating bearings are all made by loose forming-molding method. The sliding bearings made of this kind of materials are strictly required due to high load, special movement form, and foreign matter mixed in. Scorching occurs due to various temperature conditions, insufficient oil supply, improper maintenance and other reasons. Under the strict conditions that ordinary sliding bearings cannot las...
