By any chance do you mean Interference? This term would apply to Automobiles and to Baseball, the categories you listed this question in. In an automobile engine the term interference describes an Interference engine which is a type of internal combustion engine where in the event of a serious valve train failure, or a 180 degree timing error, could lead the valves and pistons to strike each other. The most common cause of this a broken timing belt, but a catastrophic timing chain failure can also bring about this situation.

In baseball, interference is an infraction where a person illegally changes the course of play from what is expected. Interference might be committed by players on the offense, players not currently in the game, catchers, umpires, or spectators; each type of interference is covered differently by the rules.

Friction is more on irregular surfaces.

The lubricant fills the irregularities and makes the surface smooth and thus reduces friction.
What a lubrication does is reduce the friction by forming a smoothe layer in between the two surfaces.

Lubricants also reduce heat :P Hope That Helped :)
By eliminating solid-solid sliding contact. A solid is defined as a material that can support shear (lateral force). When two solids come into contact, imperfections in the surface interferer with each other and resist slide by their shear strength. Liquids or macroscopic balls of graphite (dry lubricant) flow or roll to reduce shear forces the result in friction's Lubricants can reduce the corrosion particles and reduce wear and tear with the help of molecular participles in lubricant oil.
