Abstract

This paper describes the production and permeation measurements of three different aluminide coatings on the surface of DIN 1.4914 martensitic steel (MANET II). The coatings were produced by vacuum plasma spraying pure aluminium (approximately 100 um) on to the steel, which was subsequently heat treated to produce an aluminide layer on the MANET. The relationship between the aluminium content of the coatings and their effectiveness as permeation barriers, due to the greater or lower resistance to crack formation was manifest. The coatings with a lower aluminium content presented the largest permeation reduction (2 orders of magnitude).
