摘要: The impact testing is an efficient experimental method that enables the quantitative and qualitative determination of fatigue resistance mono- multilayer coatings deposited on various substrates, which was not possible with common methods previously available. In this paper assessment working under cyclic loading conditions by means dynamic presented. failure mode, such cohesive or adhesive, investigated determined using scanning electron optical microscopy, as well EDX analysis. Critical values stress components, responsible for distinctive modes coating substrate system are obtained limits aluminide illustrated in simple diagrams containing load versus number successive impacts examined aluminide-P91 can withstand.
