It is shown that in samples of ceramics based on SiC, the total sputtering of silicon atoms is 1.7 times high than that of carbon atoms, and in samples of ceramics based on TiO2, the total sputtering of oxygen atoms is 3.5 times more than that of titanium atoms, at energy of helium ions 0.12 MeV. Due to the sputtering of more silicon atoms than carbon in SiC and more sputtered oxygen atoms than titanium in TiO2, after the dissociation of SiC and TiO2, the conductivity should increase, that is, the "surface" electrical resistance of the irradiated (front) side of the samples should decrease.
