SELF-LUBRICATING SYSTEMS FOR HIGH TEMPERATURE TRIBO-APPLICATIONS - HOTselflub

Project summary

Many high temperature manufacturing processes run with uncontrolled friction conditions resulting in high energy consumption and high wear. The only solution available to control friction at temperatures over 300°C is to rely on solid lubricants. However, they come with limitations such as added costs, need to clean the parts and environmental concerns. The aim of HOTselflub is to develop novel self-lubricating (self-lub) concepts to control friction in the range of 300°C to 1000°C. These concepts will be implemented as bulk and as coatings using several deposition techniques on novel additive-manufactured ceramic-based composites to obtain superior high temperature properties, besides self-lubrication. In those applications where the use of solid lubricants is inevitable due to severe contact conditions , the developed self- lubricating surfaces will be tailored to have synergy with solid lubricants, enabling the use of more environmentally friendly compounds.
