炭素多孔烧结材料,是在压制和烧结后把熔点低的铝合金在熔融状态下,浸入炭素内部形成的一种新型复合材料。用这种新材料制作刮片密封件,具有重量轻(比重:2.3克/厘米~3)自润性好(与镀铬型面配付磨擦系数相当低),线膨胀系数小,耐磨,耐温以及加工容易等优点,特别是它在工作中对缸体型面造成的磨损和震纹很小,引起了大家的重视。其缺点 Carbon porous sintered material is a new type of composite material formed by impregnating carbon into molten aluminum alloy with low melting point after being pressed and sintered. With this new material to make the blade seal, it has the advantages of light weight (specific gravity: 2.3 g / cm ~ 3), good self-lubrication (matched with chrome plated friction coefficient), low linear expansion coefficient, As well as the advantages of easy processing, especially in the work of the cylinder surface caused by wear and shock patterns are small, aroused everyone’s attention. Its shortcomings
