抄録

MIM is an important method in the metal forming technology. Though, this process is incomplete, and still has problems in each processing step. Especially in the debinding step, there are many problems. In an actual producing process, the thermal debinding method is still used, and this method needs long debinding time. Also, the size of products is limited, and the metal powder is oxidized in this method. As a method to overcome these problems, the solvent debinding process is used recently. This method is an efficient debinding method. Though organic solvents are used in this method, they are poisonous. These solvents will harm human health and environment. For this reason, a debinding method which uses super critical dioxide(CO₂) is desirable. Using this method, quick debinding is possible, and a thick green body can be debinded. Moreover, the solvent used in this method is safe and harmless for environment.
