Abstract
A sliding material used under a boundary lubricating conditions or mixed lubricating condition, and having improved, wear-resistance, low-friction property, and seizure-resistance, and consisting of (a) 10 to less than 69% of polyimide and/or polyamide-imide, from more than 30 to 68% of graphite, and, 1 to less than 30% of polytetrafluroethylene, MoS.sub.2, Pb, and/or BN, or (b) 20 to 90% of polyimide and/or polyamide-imide, and from 0.5 to 20% clay, mullite, silica, and/or alumina, and at least 5% and balance of graphite.
Claims7
A sliding material for use under boundary lubricating condition or mixed lubricating condition, consisting essentially of from more than 30 to 60% by weight of graphite, from 1 to less than 30% by weight of at least one lubricant selected from the group consisting of polytetrafluoroethylene, MoS.sub.2, Pb, and BN, and from 10 to less than 60% by weight of a polyimide and a polyamide-imide.
A sliding material for use under a boundary lubricating condition or mixed lubricating condition, consisting essentially of from 20 to 90% by weight of a polyimide and a polyamide-imide, from 0.5 to 20% by weight of at least one friction-controlling agent selected from the group consisting of clay, mullite, silica, and alumina, and, at least 5% by weight graphite.
