説明

<p>The seizure resistance in ironing of stainless steel and aluminum alloy cups was improved by using a TiCN-based cermet die having fine lubricant pockets on surface made by shot-peening and polishing. The seizure resistance for a die having lubricant pockets of an appropriate surface shape became higher than that for a polished surface having very fine surface roughness. The friction was reduced by the liquid lubricant being squeezed out from the pockets during ironing, then the lubricant film became thick due to much amount of remaining lubricant in ironed cups. The TiCN-based cermet die having fine lubricant pockets was applied to forward extrusion of aluminum alloy billet. The seizure resistance for the die having lubricant pockets was improved. It was found that the use of the TiCN-based cermet die having lubricant pockets is effective in preventing seizure in ironing of stainless steel and aluminum alloy cups and forward extrusion of aluminum alloy billet.</p>
