This paper reports on a modified diamond jet HVOF spray gun, which makes it possible to produce layers of stainless steel and nickel alloys with very low levels of oxide and porosity. The corrosion behavior of these layers is compared with that of coatings produced with a conventional HVOF gun. Cross-sectional examinations carried out before and after corrosion testing show where and when corrosion attacks occur. Paper includes a German-language abstract.
