Abstract: Lack of a standardized method for testing the adhesive strength of ice has hampered efforts to understand ice adhesion and development of low-adhesion materials. However, there are numerous standards for testing adhesive joints. Here, we describe our adaptation of the 0° cone test for measuring the adhesive strength of ice in shear, substituting ice for the adhesive. The main advantage is its simplicity in sample preparation and testing. This paper describes our test procedure and results for ice bonded to stainless steel, aluminum, and several coatings applied to aluminum. From this study, we found that the measured adhesive shear strength of ice bonded to stainless steel increased with strain rate, which follows the same general trend as the cohesive shear in ice, except that the failure strengths were about one tenth that of the estimated cohesive shear strength. Coating aluminum reduced the bond strength by a factor of 3. There was little difference in the bond strength measured for the coatings that were tested. The adhesive strength of ice bonded to stainless steel is about the same as for coated aluminum.
