When constructing a beam dump for a fusion device, one faces several challenges and constrictions: It must be vacuum compatible, resistant to temperatures and radiation, should neither gas out nor deteriorate, should take up as less space as possible and obviously also should absorb microwave radiation well. As possible candidates, the group of ceramic metal oxide layers have been suggested, from which three different material systems have been produced by atmospheric plasma spraying and investigated: Titanium oxide, chromium oxide and an aluminum-titanium oxide compound material. Both pure titanium oxide and chromium oxide don’t show the absorption necessary, but Al2O3/TiO2 (60/40) is very promising and will be presented in the following.
