Abstract :
With the current technological development the use of materials is very dominant. In the world of engineering there are two types of material, namely metallic and non-metallic. As a base material used election takes concrete data about the material. This study aimed to investigate microstructure and hardness of top compression and 2nd new standard compression piston rings, new non-standard piston rings and standard piston rings used on the 135cc Yamaha. The hardness values of top compression piston rings new standard Yamaha 135cc had a hardness value of 496.957 VHN, the top compression piston rings standard used decreased with a hardness 427.711 VHN. Top compression piston rings non-standard had a hardness below the top compression piston rings new standards with a value of 408.497 VHN hardness. In the 2nd compression piston rings new standard Yamaha 135cc had a hardness value of 315.288 VHN and the 2nd compression piston rings standard used decreased by hardness 281.239 VHN. The 2nd compression piston rings non- standard had a hardness below the 2nd compression piston rings new standards with 243.492 VHN hardness value.
