This paper compares the corrosion, friction, and wear properties of thermally sprayed aluminum bronze coatings developed for use on plain bearing surfaces. It explains how the coatings were produced, characterized, and optimized for the intended application. Paper text in German.

This study examines stainless steel and Hastelloy C coatings sprayed using commercial HVOF equipment. Porosity and oxygen content have been measured under various spray conditions and laboratory corrosion tests have been carried out using electrochemical techniques. The report first summarizes major results obtained in the laboratory evaluation, then presents the results of marine exposure testing for up to six months. It concludes with detailed comparisons between the two. Paper includes a German-language abstract.

This paper provides a general overview of arc spraying and its various uses in industry. It discusses the basics of the technique, the types of wires and powders used, and typical applications for a wide range of arc-sprayed metals and composites. It also discusses special cases and considerations such as wear protection in corrosive atmospheres, high-temperature corrosion protection, surface rebuilding and reprofiling, coating thickness, and the effect of different elements. Paper includes a German-language abstract.

Though a large literature exists on thermal spray coating, there have been few attempts to directly observe molten droplets as they land on a substrate, freeze, and coalesce into a solid layer. In this study, investigators photograph the impact of tin droplets landing on stainless steel surfaces at high speeds. They also measure the effect of substrate temperature and surface roughness on deposition efficiency, the fraction of coating material that adheres to the surface. The paper describes the apparatus used to create the tin droplets and record their impact with the target. It also provides a detailed review of the test results and discusses the practical implications of the study. Paper includes a German-language abstract.
