Long Story short: 

Your ultimate still does physical damage = affected by armor = black cleaver will increase your damage vs high armor targets

Long Version:

lets say 100 armor half the physical damage you deal !

You deal 1000 damage over 3sec vs a target without armor = 500 damage after 3sec

You deal 500 damage over 3sec vs a target with 100 armor = 125 damage after 3sec

You maybe noticed something ... his ultimate is affected by armore twice (if it would work like this)

How it rly works:

You deal 1000/2 =  500 damage over 3sec vs a target with 100 armor = 500/2 = 250 damage after 3sec
