Abstract
Official abstract text for this publication.
A multilayered sliding member 1 comprises a backing plate 2 having a steel plate; and a porous sintered alloy layer 3 which is integrally joined to one surface of the backing plate 2 and is composed of 25 to 60% by mass of nickel, 2 to 7% by mass of phosphorus, and the balance copper.
First claim
Opening claim text (preview).
1 . A multilayered sliding member comprising: a backing plate having a steel plate; and a porous sintered alloy layer which is integrally joined to one surface of said backing plate and is composed of 25 to 60% by mass of nickel, 2 to 7% by mass of phosphorus, and the balance copper. 2 . A multilayered sliding member comprising: a backing plate having a steel plate; and a porous sintered alloy layer which is integrally joined to one surface of said backing plate and is composed of 25 to 60% by mass of nickel, 2 to 7% by mass of phosphorus, 3 to 8% by mass of tin, and the balance copper. 3 . The multilayered sliding member according to claim 1 , wherein the steel plate is formed of a ferritic, austenitic, or martensitic stainless steel plate, and the one surface of said backing plate is one surface of the stainless steel plate. 4 . The multilayered sliding member according to claim 1 , wherein the steel plate is formed of a ferritic, austenitic, or martensitic stainless steel plate, said backing plate further has a nickel coating covering one surface of the stainless steel plate, and the one surface of said backing plate is one surface of the nickel coating. 5 . The multilayered sliding member according to claim 1 , wherein the steel plate is formed of a rolled steel plate for general structure or a cold rolled steel plate, said backing plate further has a nickel coating covering one surface of the rolled steel plate for general structure or the cold rolled steel plate, and the one surface of said backing plate is one surface of the nickel coating. 6 . The multilayered sliding member according to claim 1 , wherein said porous sintered alloy layer includes a matrix containing a copper-nickel alloy and a nickel-phosphorus alloy phase crystallized at grain boundaries of the matrix, and wherein the matrix has a micro Vickers hardness (HMV) of at least 170, and the nickel-phosphorus alloy phase has a micro Vickers hardness (HMV) of at least 600. 7 . The multilayered sliding member according to claim 1 , further comprising a coating layer filled in the pores of, and secured on one surface of, said porous sintered alloy layer and containing a synthetic resin. 8 . The multilayered sliding member according to claim 7 , wherein the synthetic resin includes at least one synthetic resin selected from a fluororesin, a polyacetal resin, a polyamide resin, a polyphenylene sulfide resin, a polyetheretherketone resin, and a polyamideimide resin.
