Abstract
The powder metallurgy process can achieve producing products with high-performance materials, and also it enables the product to have a high standard of dimensional precision compared to the Ingot metallurgy process. Therefore, sintered component products have been adopted for many automotive parts, and the number of these cases predicted to soar year after year. This paper shows two topics regarding the development and productization of advanced powder metallurgy products.
One of the topics is about the aluminum-based high-performance alloy using rapid solidification aluminum alloy powders. Main features of this material are high strength, wear and abrasion resistance, and heat resistance. This material is used for the cylinder liner of motorcycle engines.
The other topic is about the warm sizing technology, which is able to complete sizing process and attain high precision simultaneously by hardening a material while pressing in a die. This technology is applied for the parts of the high performance oil pump.
