Effects of Molding Pressure and Sintering Temperature of Silicon Particles on Oil Content and Lubricating Characteristics of Particle-Dispersed Aluminum Sintered
Kenichi TSURU and Susumu MATSUMOTO
Abstract:A clear yield point was not seen in the tensile strength of the aluminum sintering body. As for the molding pressure, 170MPa was the upper limit value. Hardness, the radial crushing strength increased, but the oil content. As for the sintering temperature, 545 were the upper limit values. Hardness, the radial crushing strength increased, but the oil content increased to 545, too. The friction examination of molding pressure 170MPa showed limit PV value 6.46MPa.m/s. The friction examination of sintering temperature 545 showed aspect pressure 17MPa. The life examination maintained friction temperature to approximately 40 until 30 hours.
