Abstract: The invention relates to a method for producing a coating for absorption of neutrons produced in nuclear reactions of radioactive material which can be applied in an economically feasible and simple manner, increases the effectivity of absorption, enables greater variability of base material used and variability of shape of said shielding elements and in particular the production of lighter shielding elements with at least the same absorption quality. The invention also relates to a method for producing a coating for absorption of neutrons produced in nuclear reactions of radioactive materials. At least one part of a shielding element consisting of base material is provided at its surface designed therefore with a layer made of an element with a high neutron capture section and a metallic element in a dispersion bath. Said metallic element can be deposited by electrolytic or autocatalytic means.

Abstract: A turbocharger comprises a shaft connecting a turbine wheel, which is disposed in a turbine housing, to an impeller wheel. Between the two is a bearing system having a bearing housing and bearings for the shaft disposed therein. The shaft is fitted with at least one heat insulation between the turbine wheel and the bearing system, of which the heat conductivity is lower than that of the portions of the shaft which are adjoining said insulation and which hampers heat transmission through the shaft.
