Process characteristics and parameters of ANOF as well as that special logarithmic relation of the layer formation parameters which is valid for the spark region are discussed. By calorimetric investigation it can be shown that the greatest share of electric energy will be transformed to heat and that the current quantity of ≈ 1.1.A · s · cm −2 is characteristic for the incubation period before spark discharge during the gas — solid reaction of aluminium coating.
