説明
Huge amount of wasted lubricants have become a great nuisance of environmental issues. Dry deep-drawing processis attractive toward zero emission of lubricants but it has a great difficulty in application to metal sheet forming in general.As one of the most promising methods, use of the die coated diamond-like carbon thin film (DLC) is high-lighted becauseof their excellent tribological properties. However, there is a fatal problem of exfoliating from the tool surface inDLC under the high-pressure conditions. Influence of materials, surface asperity of substrates and interface layers on improvementsin adhesion were studied with use of a ball-on-disk type tribometer. The results show that the surface roughnessof substrate becomes larger, the adhesion of DLC becomes stronger. From the results of the field test, the use of a diecoating DLC has been found to eliminate the need for any lubricant to prevent adhesion of aluminum to the die material.In addition, the rougher surface die, 2.98 mmRz, prolong the die life up to 10,000 deep drawing operations.
