No they are not.


An ergosphere is the are around two black holes that are revolving around each other. Where the black hole is influencing an objects movements. Where as accretion disks are found in more than just black holes.

"Accretion disks are ubiquitous features in the universe and can be found around smaller stars or stellar remnants, in close binary stars, in the centers of spiral galaxies, in quasars, they form also in gamma-ray bursts."

An accretion disk is basically a big dense chunk of materials that is revolving around a big gravitational force. And eventually it revolves into the force itself. Think of a big moving asteroid belt that revolves a gravitational body that eventually hits it.
