Carla has been at the centre of high-profile storylines on the show since her introduction in 2006 - including her recent rape plot with evil Frank Foster.
Speaking to The Sun's TV Buzz magazine, King hinted that she is unlikely to leave the cobbles anytime soon.
"I've always said I'll keep playing Carla till I get bored of her," the actress explained. "And with someone like Carla, there's never much chance of getting bored."
King also praised co-stars Andrew Lancel and Chris Gascoyne, who play twisted Frank and troubled Peter Barlow respectively.
"I call [Andrew] my very own Stephen Fry as he's full of trivia," she commented. "I'll tell him, 'You're boring me with all these facts! Will you shut up now?' But we've got chemistry that can be hard to find in this business. Andrew keeps me alive - he keeps me going."
She continued: "I love working with Chris Gascoyne so much. It's like working with your granddad. Honestly, he gets older by the day, but I know I'm going to have to give him back to Jane Danson [Leanne] at some point because she misses him dearly."
King's full interview appears in the next issue of TV Buzz, which is free with The Sun on Saturday.
Coronation Street continues tonight at 7.30pm and 8.30pm on ITV1.
