6.9 Patch notes, Turrets and structures Question.

Hey everyone, just want to clear up a question that I had while reading the patch notes for tomorrow. Do items such as black cleaver, wits end, effect turret armor ratios per hit? If so are they also effected by champion skills/spells/passives with like effects (such as Kayle's passive or Jayce's R)

Thanks for responces in advance.
