摘要:
A sliding bearing for an internal combustion engine including a copper-based bearing alloy including silver and tin upon which an overlay is applied. The overlay comprises resin and MoS2, and the adherence of the overlay to the alloy is enhanced by a roughened alloy surface formed of grooves extending in the sliding direction.
摘要:
A slide bearing is described with a bearing metal layer on copper basis as applied to a carrier and a running layer made of an alloy of aluminum and tin which is applied physically onto the bearing metal layer in vacuum. In order to combine favorable resistance against wearing with a low inclination towards jamming with advantageous tribological properties it is proposed that the bearing metal layer consists of an alloy with 4 to 8% by weight of tin, 0.6 to 1% by weight of silver, 1 to 2% by weight of an iron phosphide and 0 to 0.15% by weight of carbon, preferably in the form of graphite, and the remainder of copper.
摘要:
The copper-based sliding material has improved seizure resistance, even if it is free of Pb, and enables thinning of the overlay. The copper alloy provided consists of from 0.1 to 2% of Ag, from 1 to 10% of Sn, and the balance consisting of Cu and unavoidable impurities and, further said Ag and Sn do not essentially form the secondary phases but are in complete or essentially solid-solution state in the Cu matrix.

摘要:
An object of the present invention is to provide a sliding member suitable to a soft mating member low in hardness. The present invention relates to a sliding member for sliding with a mating member having a ferrite phase at least on a surface thereof, the sliding member including a coating layer containing a binder resin, molybdenum disulfide, and hard substance particles.
摘要:
There is provided a composite material, which exhibits the properties of copper alloy and aluminum alloy, and which has improved wear-resistance and seizure-resistance. By frame-spraying is prepared a copper-aluminum composite material, which consists of copper or first copper-alloy (for example Cu—Pb alloy) including at least unmelted phase and aluminum or first aluminum-alloy (for example Al—Si alloy) including at least melted phase.
