项目摘要

The Purpose of this study is to develop new fabrication process of RB ceramics by using injection molding, and to apply them to tribo-elements.New RB ceramics fabricated by using injection molding have been developed, and their size reduction rate during carbonization and mechanical properties were clarified in 2003. The new fabrication process of RB ceramics were as follows ; The form of the mixture of RB ceramics and phenol resin was molded by injection molding, and then the new RB ceramics were fabricated by carbonizing the form in nitrogen gas at 900 ℃. It was clarified that the size reduction rate of the newly developed RB ceramics was less than 5% which was one-fifth of that of conventional RB ceramics (25%) made by using press molding. Then, it was also clarified that young's modulus of the newly developed RB ceramics was 15GPa, and the compressive strength was 270MPa which was about 4.5 times higher than that of the conventional RB ceramics.Tribological properties of the newly developed RB ceramics sliding against alumina, bearing steel ball and austenitic stainless steel under dry and oil lubricated conditions were clarified in 2004. As a result, it was clarified that a newly developed RB ceramics showed superior tribological properties under dry and oil lubricated conditions. Therefore, the newly developed RB ceramics fabricated by using injection molding are expected to be practically applied to the materials of sliding bearing.The effect of temperature on tribological properties of the newly developed RB ceramics was clarified in 2005. As a result, it was clarified that the newly developed RB ceramics showed superior tribological properties under dry condition at high temperature. Therefore, the newly developed RB ceramics are expected to be practically applied to the materials of the dry type clutch plates.

本研究的目的是开发一种新的注射成型RB陶瓷的制备工艺，并将其应用于摩擦元件，2003年开发了一种新的注射成型RB陶瓷，并阐明了其在碳化过程中的尺寸减小率和机械性能。RB陶瓷的新制备工艺为：将RB陶瓷与酚醛树脂混合物注射成型，然后在900 ℃氮气气氛中碳化，制备RB陶瓷。结果表明，新开发的RB陶瓷的尺寸减小率小于5%，这是使用压制成型制成的常规RB陶瓷（25%）的五分之一。2004年，研究了新型RB陶瓷的弹性模量为15GPa，抗压强度为270MPa，是传统RB陶瓷的4.5倍。研究了新型RB陶瓷在干摩擦和油润滑条件下与氧化铝、轴承钢球和奥氏体不锈钢的摩擦学性能。结果表明，新开发的RB陶瓷在干摩擦和油润滑条件下均表现出优良的上级摩擦学性能。2005年，研究了温度对RB陶瓷摩擦学性能的影响。结果表明，新开发的RB陶瓷在高温干燥条件下表现出优异的上级摩擦学性能。因此，新开发的RB陶瓷有望实际应用于干式离合器片材料。
