A rotary internal combustion engine includes a main rotor housing that has a peripheral wall that circumscribes a rotor cavity, a first interface surface and a second interface surface. A rotor is disposed within the rotor cavity. First and second side housings are secured against corresponding first and interface surfaces of the main rotor housing. The main rotor housing, the first side housing and the second side housing are formed from an aluminum alloy and at least one of the first interface surface and the second interface surface include an anti-fretting coating.
