摘要： PROBLEM TO BE SOLVED: To solve such a problem that, when Cu-plated solid lubricant is mixed with Cu-Sn alloy powder and sintered, the solid lubricant is firmly joined with a copper alloy matrix since Sn in the alloy powder is diffused into the Cu plated layer in a process where the ordinary sintering phenomena such vacancy elimination and grain boundary migration are developed however the conformability of the sintered copper alloy is deteriorated.
SOLUTION: A lead-free copper-based sintered sliding material is obtained by dispersing the solid lubricant grains with copper-based coating, of MoS
2 , graphite, WS
2 , Bn, etc., into the matrix composed of Cu-Sn based alloy grains containing 0.1-15mass% Sn and the balance essentially Cu, wherein the hardness of the copper-based coating under sintered state is lower than the hardness of the matrix.

摘要： PURPOSE:To form a sliding layer having superior properties by scattering a uniform powder mixture of Al alloy powder and solid lubricant grains or further hard grains on the surface of a strip-like body made of Al alloy and then performing heating and compression under specific pressure and temp. conditions. CONSTITUTION:A uniform powder mixture 2 which has a composition consisting of, by volume, 1-30% of the grains of solid lubricant having stretchability, such as MoS2, graphite, and BN, and the grains of soft metal, such as Pb, In, Cd, and Sn, 0.5-10% of the grains of hard ceramics, such as the oxides, carbides, nitrides, and borides of metals, and the balance Al or Al alloy grains is laminated on a supporting plate 1, such as Al alloy strip-like body, steel plate, and copper alloy plate, and pressurized by a roll 3. The resulting preformed body 4 is heated up to about 600 deg.C in a heating furnace 5 to undergo the melting of the Al powder and then pressurized and solidified by means of a outlet roll 6 of the furnace 5, by which a composite Al plate 7 having a sliding layer where the solid lubricant powder and the hard powder are uniformly dispersed in the Al alloy is formed. This plate is joined to a steel strip 9, by which an Al type composite sliding material 14 excellent in lubricity can be produced.

摘要： PROBLEM TO BE SOLVED: To reduce the strain at the junction interface to hold good radiation characteristics, by adding ceramics or metal grains having a less thermal expansion to Cu. SOLUTION: A substrate is composed of at least two plates having different thermal expansion coefficients i.e., a sintered plate composed of Cu or Cu alloy grains 20-70 vol.% and at least one kind of grains selected among ceramics and metals having smaller thermal expansion coefficients than that of Cu and ceramic plate. The metal is selected among Mo, W and Si. This reduces the thermal expansion coefficient difference between the ceramics and the metal for the metal substrate, and hence reduces the strain at the junction interface to hold good radiation characteristics.

摘要： PURPOSE:To improve the wear resistance and seizure resistance of a coppery sintered sliding material used under heavy load conditions, high peripheral speed conditions, and/or boundary lubrication conditions and also to improve the wear resistance, seizure resistance, and corrosion resistance of a coppery sintered sliding material used under corrosive conditions resulting from the deterioration of lubricating oil, besides those conditions. CONSTITUTION:Aluminum nitride grains of 1-30mum average grain diameter are added to Cu or Cu alloy by 0.2-15wt.% and dispersed. Further, if necessary, either or both of 5-40wt.% Zn and 5-50wt.% Ni and/or 0.1-5wt.% Ag is added. By this method, this material can contribute toward improving the properties of sliding members used under increasingly severe service conditions.
