Development of a Slurry Erosion Test standard of Industrial Maintenance Coatings

Development of a Slurry Erosion Test standard of Industrial Maintenance Coatings
Available for download

Over the past several years, the Bureau of Reclamation’s Materials Engineering Research Laboratory has been developing and refining a test method to evaluate a coating’s resistance to erosion damage in sediment-laden immersion exposure. This test has initially been utilized as a screening/ranking method in selection of new coatings for the aforementioned severe service environments.

Over the past several years, the Bureau of Reclamation’s Materials Engineering Research Laboratory has been developing and refining a test method to evaluate a coating’s resistance to erosion damage in sediment-laden immersion exposure. This test has initially been utilized as a screening/ranking method in selection of new coatings for the aforementioned severe service environments. However, the goal is to develop the procedure into an ASTM standard test method. This paper details the procedure developed by Reclamation in collaboration with the ASTM standards committee and provides initial results from several coating types. Weight loss is measured during extended testing in order to evaluate and compare coating wear over time. It is expected that this standard will be useful in selection of coatings intended for raw water immersion service, particularly in situations where there are entrained solid particulates present in flowing water.

Cavitation erosion of the rudder has been a serious problem in the high-speed container ship industry. It is well known that the lifetime of a conventional coating system is about 6 months against cavitation bubble collapse. Although STS 316L stainless steel has been applied to prevent such a problem, there are several drawbacks such as high repair cost and poor workability.

Adhesion performance is required for every coating system. The adhesion between coatings and substrates is one of the most critical determining factors in the overall success of any coating material. Material design and formulation are key components of high-performance coatings and rely heavily on the accurate measurement and evaluation of adhesion in the coating systems.
