Development of super-long-life tools with functionally graded materials
Published May 23, 1999 by SAE Australasia in Australia
A new super-hard material has been developed based on the technology gained through the research and development of ceramic production methods. The new super-hard material has the characteristics such that its surface has higher hardness, durability, and its inside is stronger and more tenacious including the internal current layer change physical properties and the components at a distance from the surface. This functionally graded material presents drills, reamers, and dies that are hard to break or wear. Production line tests have proved these to have the same or higher strength and have higher tenacity than the alternative high-grade, super-hard material, yet last 1.5 to 8 times longer.
