The current distribution in an electrolytic cell that is free of polarization. The first coat of paint applied to a surface. The maximum or minimum value at the normal stress at a point in a plane considered with respect to all possible orientations of the considered plane. On such principal planes the shear stress is zero. There are three principal stresses on three mutually perpendicular planes.
Multiaxial stress refers to either biaxial or triaxial stress.
Anchor pattern on a surface produced by abrasive blasting or acid treatment. The threshold value of the corrosion potential that has to be reached to enter a protective potential range. The term used in cathodic protection to refer to the minimum potential required to suppress corrosion. A range of corrosion potential values in which unacceptable corrosion resistance is achieved for a particular purpose.
