铜—石墨材料广泛用于高速滑动条件下工作的摩擦部件(如滑动电触头等)。本文所研究的铜-石墨材料,是用-1铜粉和C-1胶体石墨配成混合料,用双向压制成压坯,然后在950℃的氢气介质中烧结2h得到试样,再进行精整,在某些情况下,还在450℃的温度下对其退火1h。然后测量其硬度、冲击韧性、横向抗弯强度和抗压强度。抗压试验的试样尺寸为:直径×高=10×15mm。 Copper - graphite materials are widely used in high-speed sliding friction parts work conditions (such as sliding electrical contacts, etc.). The copper-graphite material studied in this paper is compounded with -1 copper powder and C-1 colloidal graphite, pressed in two-way into compacts and then sintered in a hydrogen atmosphere at 950 ℃ for 2h to obtain a sample, In total, in some cases, it is also annealed at a temperature of 450 ° C for 1 hour. Then its hardness, impact toughness, transverse flexural strength and compressive strength were measured. The compression test specimen size: diameter × height = 10 × 15mm.
