本文叙述了新开发的氮化硅陶瓷气门挺柱，它不仅成本低，而且具有比烧结合金气门挺柱更好的抗磨损性及抗胶着性。在不使用低应力材料的情况下，将一圆盘形陶瓷片直接钎焊到钢制的气门挺柱基体上，无需经磨削加工便形成凸起面使磨损下降。用磨损试验来确定氮化硅的最佳种类以及最佳表面粗糙度。经发动机耐久性试验证明它具有权好的抗磨损性、抗胶着性。因此，这些陶瓷气门挺柱将首次应用于１９９３年型发动机上。 This article describes the newly developed silicon nitride ceramic valve tappet, which not only low cost, but also has better wear resistance and resistance to seizure than the sintered alloy valve lifter. Without the use of low-stress materials, a disk-shaped ceramic plate is brazed directly to a steel valve tappet body without the need for grinding to form a convex surface to reduce wear. Wear tests were used to determine the best type of silicon nitride and the best surface roughness. After the engine durability test proved it has the right anti-wear, anti-seize. Therefore, these ceramic valve tappet will be the first time applied to 1993 type engine.
