From Dresser-Rand
Thermal spray coatings, of which HVOF is one, are an important enabling technology used to enhance the performance of materials in a diverse range of industrial applications. One area which has received relatively little attention is the effect of thermal spray coatings on the elevated temperature high cycle fatigue behavior of metallic substrates. This paper presents the results of rotating beam fatigue testing conducted on 403 stainless steel HVOF coated with three materials which have been or are being considered as candidates for blade coatings. Furthermore this paper will outline how various mechanical and physical attributes of both the coating and substrate influence this behavior.
