Latest Patents

Akutagawa holds a patent for a sintering method designed for creating high carbon ferrous sliding elements. This method involves two principal stages. The first stage consists of sintering green compacts in a conventional manner. The second stage follows immediately, where the sintered compacts are held at an elevated temperature, below the sintering temperature, in a carburizing gas. This process allows for the diffusion of essential components, such as carbon, into the compacts, particularly for ferro-carbide materials used as sliding elements. Additionally, the sintering box utilized in this method may feature holes of specific sizes and distribution densities to facilitate the efficient removal of any lubricant initially added to the compacts.
