Description
Summary:It was established that existing methods show low accuracy when assessing the durability of coatings. Furthermore, they don't allow assessment of the contribution into durability of structural components and fillers for thermodiffusion and polymer-composite coatings, respectively. A method to evaluate durability of thermal diffusion chrome coatings on carbon steel and gray cast irons has been developed - the speed ν^sub p^ of destruction of the structural components of the coating. In addition, the destruction of each structural component is characterized by a constant value of destruction speed ν^sub p^ and potential [varphi], and their sharp vibrations are in complete destruction of the coating and the beginning of the destruction of the base metal. From the start of the test until the abrupt change in the rate of destruction ν^sub p^, which is found on the curve ν^sub p^ - τ is the assessment of durability coating τ^sub δ^ hat is specified with the curve [varphi] - τ. Accuracy of the durability decreases from ^plusmn;30 min to ±2 min.
