| 1. A reaction control turbine blade, comprising:
a Ni-base superalloy;
a reaction control material; and
an aluminum diffusion coating, wherein the reaction control turbine blade is formed by applying the reaction control material
to a surface of the Ni-base superalloy before applying the aluminum diffusion coating to the Ni-base superalloy coated with
the reaction control material, wherein the reaction control material is an alloy or solid solution that consists of one or
more elements selected from the group consisting of Co and Ru, wherein the alloy or solid solution consists of from 0 to 10
at. % of Co and from 90 to 100 at. % of Ru, or consists of from 50 to 80 at. % of Co and from 20 to 50 at. % of Ru, wherein
the at. % sum of Co and Ru equals 100 at. % of the reaction control material.
