PublicationWhy not using ceramics - trends from ceramics research( 2017)
;Stepanyan, Marina ;Seifert, Gerhard ;Weiß, Torsten ;Klein, Tiago BorsoiWithin the Fraunhofer AdvanCer Alliance/DE, four institutes have pooled their capabilities to form a coordinated range of services aimed at using advanced ceramics in the creation of individual system solutions for industrial partners. Below, we present two examples from our successful project work showing the advantages of advanced ceramics in specific industrial applications.
PublicationWear of abrasive media and its effect on abrasive flow machining resultsAbrasive media were examined before and after application in abrasive flow machining to evaluate the wear of media due to the machining process. Both media were tested on workpieces under the same working conditions to study the effect of abrasive media wear on the results of the machining process. With the help of rheological and granulometric characterisation methods, it has been shown that alterations of rheological behaviour and composition of the abrasive medium as well as particle shape and size are responsible for the degradation of the abrasive efficiency. The increasing viscosity of the abrasive medium and progressing rounding of the large abrasive particles as a result of the machining process are the main factors that cause a decreased material removal rate and reduced surface quality.
