Not 100% sure, but I'll tell you what it sounds like. Whenever you burn a motor, some of the propellant reforms on the nozzle. You can scrape it off, or let it burn off the next time you use it. That would be the "slag build-up."

Nozzle "throat erosion" would be a slow, continual loss of mass in the nozzle throat due to graphite burning off.

"Co-efficient" would indicate numbers to use in equations when calculating burn characteristics.

If I'm wrong, someone will come along and let you know.

By the way, the title of your post is not likely to attract the right people.

Re-post or re-title your post so that people who are interested in those things know what you're asking. "rocket" is not a title that is going to get many people's attention.
