The Peel Test (Figure 3c,d) uses an open planar configuration and thus can be used with saline spray ice and accretion ice in addition to freshwater polycrystalline ice. The Double Lap Shear Test (Figure 3b)4 is an ASTM standard test index test (ASTM D3528) that is configured to assess a flat test coupon (planar interface). Now known as an industry standard, the Zero Degree Cone Test (ZDCT, Figure 3a)3 is widely used as an index test for screening the adhesion of freshwater ice to coatings under development. (Raw data files available upon request.)ĮRDC-CRREL has a versatile set of ice adhesion testing methods that can both serve as an index test for comparing a set of samples during the R&D phase of a project or as a more quantitatively rigorous measurement on promising candidate coatings for low ice adhesion applications.
Weathering tests and durability testing availableĪ standard summary report is provided for each group of specimens tested.Small- to mid-sized laboratory scale specimens (30 x 50, 100 x 150 mm) or large scale specimens (1 x 1 m) can be accommodated.
Polycrystalline freshwater ice, saline, or freshwater spray ice.Flat or curved specimens, closed or open configurations.Temperature capabilities range from −5☌ to −40☌.Tensile (Mode I) or shear (Mode II) fracture modes.At least five replicates were used for each sample type. Error bars represent the standard deviation of the average values. The apparent ice adhesion strength for commercial materials in (a) tension and (b) shear delamination modes at −8☌. The weathering processes for the data on the right are indicated in the legend. Samples on left were tested before and after being placed below water level in a Mississippi River navigation lock for a 4-month-long summer season where they were subjected to repeated draining and flooding with normal lock operations. (b) Ice adhesion test result for potential low-adhesion coatings and materials before and after weathering. (a) Ice adhesion test results for construction materials and commercial coatings. 2 Owing to the large data set of evaluated low ice adhesion coatings and materials it is easy to compare the performance of new coatings and materials to the performance of existing products.įigure 1. More recently, CRREL has performed durability testing on polyurethane rubber coatings that showed remarkably low ice adhesion after outdoor winter testing and abrasion. 1Īs seen in Figure 2, there is not a consistent trend the in durability of coatings some adhesion values have decreased while others increased and still others remained approximately the same.
In addition to testing the adhesion of ice to freshly prepared surfaces, CRREL has also performed weathering tests to verify the durability of a broad range of coatings. What it doesĮRDC-CRREL has a long standing reputation in the evaluation of coatings and materials for low ice adhesion applications in locks and dams, aviation, maritime operations, and utility installations (Figure 1).
