Abstract

Hot sheet metal forming tools are exposed to severe operating conditions which cause adhesion, abrasive wear and fatigue. This causes a reduction in tool life and increased tool maintenance costs. On the other hand, the need for eco-friendly tools has arisen. Surface modification technologies have created opportunities in the tooling industry because of their capability to reduce the thermal and mechanical wear of hot sheet metal forming tools hence extending tool life. However, the technologies have some challenges which limit their wide application and there is need for further development. The purpose of this paper is to give a review on the application of surface modification technologies in hot sheet metal forming tools. The paper also discusses future research areas in the modification of tool surfaces to reduce wear and friction in hot sheet metal forming tools.
