The electroweak corrections at the order of O(αewmt(b)2/mW2) to the partial widths of the t~2→g~+t and g~→t~1+tˉ decays (depending on the masses of the particles involved) are investigated within the Supersymmetric Standard Model. The relative corrections can reach the value of 10% in some parameter space, which can be comparable with the corresponding QCD corrections. Therefore, they should be taken into account for the precise experimental measurement at future colliders.
