Abstract

The shear strength of plasma-sprayed electroinsulating Аl₂O₃ coating has been determined for blanket modules of a thermonuclear reactor in a friction couple with 316L(N)-IG steel and BrAZhNMts9-4-4-1 bronze. An analysis of the experimental and calculated data on the influence of shear stresses on the electric insulation of blanket modules has revealed the need to decrease the coefficient of friction to permissible level [f] = 0.28 in the range of contact pressures Р = 3–500 MPa.
