摘要： An AlN dispersed powder aluminum alloy with a particular composition and structure has excellent wear resistance, seizure resistance, heat resistance, toughness and machinability. In the structure of the alloy, AlN layers are discontinuously dispersed along some of the grain boundaries of former aluminum alloy particles in the matrix of an aluminum alloy sintered body. Diffusion and sintering progresses between non-nitrided grains at areas of grain boundaries not having AlN layers, to attain strong bonding between the grains. A nitriding accelerative element such as Mg, Ca or Li is provided in some of the grains to promote the discontinuous formation of the AlN layers. Additionally, layers of a nitriding suppressive element such as Sn, Pb, Sb, Bi or S may be discontinuously dispersed at regions along some of the grain boundaries, and bonding between grains is achieved at these regions as well. The alloy is prepared by sintering a green powder compact of prescribed composition under prescribed sintering conditions.

摘要： The invention concerns copper-based sintered components for use as contact components such as clutches and brakes and is intended to provide a sintered component comprising hard particles admixed with and finely and uniformly dispersed in a primary particle of a matrix to provide improved friction coefficient, and in which the dispersed hard particles are inhibited from coming off the Cu--Sn alloy matrix during contact movement so that the sintered component is possessed of good friction contact characteristics and improved mechanical properties under dry and wet conditions. The sintered contact component comprises a copper-based sintered alloy having a structure such that 15 to 25 wt % of a hard particulate material having a maximum particle diameter of not more than 15 .mu.m and a mean particle diameter of not more than 5 .mu.m is uniformly dispersed within copper particles in an alloy matrix.

摘要： A slide member of a sintered aluminum alloy includes a matrix (1) formed of an aluminum alloy powder, and aluminum nitride films (2) dispersed along old, i.e. former original, powder grain boundaries of this matrix. When a state in which the aluminum nitride films (2) completely continuously enclose the peripheries of the old powder grain boundaries is defined as a dispersion ratio of 100%, the present aluminum nitride films (2) are discontinuously dispersed at a dispersion ratio of not more than 80%. A powder compact consisting of rapidly solidified aluminum alloy powder is heated and held in a nitrogen gas atmosphere, thereby facilitating reaction between aluminum and nitrogen through an exothermic phenomenon following deposition of elements solidly dissolved in the aluminum alloy, for forming aluminum nitride films dispersed on the aluminum alloy powder grain surfaces.

摘要： A friction material includes a composite hard grain disperse metal powder dispersed and held in a thermosetting resin matrix. The metal powder consists of a metal base comprising copper, aluminum, copper alloy or aluminum alloy and hard grains which are substantially homogeneously dispersed therein. The content of the hard grain disperse metal powder in the friction material is at least 20 percent and not more than 90 percent on a volume basis. The obtained friction material exhibits a stable coefficient of friction of at least 0.3 under dry sliding conditions while preventing the so-called semicontact phenomenon of locally coming into contact with a counter material even if a pressing load during frictional sliding is small.
