WebJan 9, 2015 · fcm= 1- ( (1-a)^2/2btf) (eq 2) 6.4.2 The coating breakdown factor is a function of coating properties, operational parameters and time. As a. simple engineering approach, fc can be expressed as: fc = a + b · t (eq 3) where t (years) is the coating age and a and b are constants that are dependent on coating properties and the. environment.
