In all the books I've read about the Korean War, tanks battles are a rare thing. Initially the ROK army and US forces had few tanks and the T34/85's had little trouble driving south. Many were knocked out by field guns, infantry anti tank weapons and air strikes the farther south they went.
The counter attack north after the Inchon landings used allied tanks to spearhead up the roads but were used mainly as support and artillery whenever the enemy was encountered.
After the Chinese entered the war and things stabilized around the 38th parallel, tanks were just fire support weapons.
I'm sure there were a few incidents of tank engagements in Korea but I can't find in my books here anything significant. There was a study done in 1954, I think, that basically all they say is that the American M26, M46, and British Centurion were very good tanks vs. the T34/85. The Sherman on the other hand, while a good tank, seems to have been mostly used as artillery.
Sorry I couldn't help much.
Good luck!
