AbstractOne way to produce coatings with high gas retaining capability is to manipulate their structure towards a nano-porous one. Combined Magnetron Sputtering and Ion Implantation (CMSII) technique was used to produce pores of 1–10 nm in tungsten layers of about 1 m in thickness. STEM, EDX, RBS, TDS and GDOES techniques were used for analyses of these layers. By heating the layer at 950C the pores size increased up to 30 nm. The total amount of Ar retained in these layers was 3.9 1020 atoms/m2 while in compact W coating of the same thickness only 2.7 1019 atoms/m2 it was found.
