under conditions of heavy load and low speed a thick film of lubricant cannot work ,under these conditions,boundary lubrication occurs.in other words ,this type of lubrication cannot persist ,and metal metal direct contact is possible for some reasons.such a situation develops when 1)the viscosity of oil is low 2)the load is fairly high 3)the viscosity of oil is low 4)a shaft starts moving from rest
The boundary is between the unsaturated zone and the zone of saturation.

Lubricants used are oil, graphite, water and synthetic lubricants.
No
Lauric acid is used to make lubricants
Lubricants.
Lubricant are not used to dampen rough surfaces. They are used to smoothen the surfaces. They reduce friction through the slippery lubricants on the surfaces.
Lubricants are solely used for reducing friction between two moving parts of a machine.
