Abstract

Superplastic forming (SPF) is an advanced manufacturing process, typically restricted to low volume and high value products, where metallic sheets are heated at the forming temperature and blow-formed into a metallic die. Ceramic dies are an emerging technology in the SPF domain, as they have a lower production cost than conventional metal tools, and have short lead-times, but their brittle nature is a limiting factor for SPF applications. Suitable surface treatments have a remarkable effect on wear resistance; hence, the scope of the research is to investigate a suitable coating solution to improve the working surface wear resistance, increasing the lifetime of the SPF ceramic dies.
