Abstract
A method and system for magnetically detecting thermal degradation of a component. A multiple of ferrous metal segments are attached to a component not within a lubrication circuit of a lubrication system with a thermally-affected bonding agent. The thermally-affected bonding agent is operable to detach at a threshold temperature at least one of the multiple of ferrous metal segments such that the at least one of the multiple of detached ferrous metal segments enters the lubrication circuit of the lubrication system. The at least one of the multiple of ferrous metal segments which detached are then detected within the lubrication system.
